[PATCH stable 6.6.y] arm64: kaslr: fix nokaslr cmdline parsing

by Chen Ridong

From: Chen Ridong <chenridong(a)huawei.com> Currently, when the command line contains "nokaslrxxx", it was incorrectly treated as a request to disable KASLR virtual memory. However, the behavior is different from physical address handling. This issue exists before the commit af73b9a2dd39 ("arm64: kaslr: Use feature override instead of parsing the cmdline again"). This patch fixes the parsing logic for the 'nokaslr' command line argument. Only the exact strings, 'nokaslr', will disable KASLR. Other inputs such as 'xxnokaslr', 'xxnokaslrxx', or 'xxnokaslr=xx' will not disable KASLR.

[PATCH AUTOSEL 6.15 1/9] fbcon: Make sure modelist not set on unregistered console

by Sasha Levin

From: Kees Cook <kees(a)kernel.org> [ Upstream commit cedc1b63394a866bf8663a3e40f4546f1d28c8d8 ] It looks like attempting to write to the "store_modes" sysfs node will run afoul of unregistered consoles: UBSAN: array-index-out-of-bounds in drivers/video/fbdev/core/fbcon.c:122:28 index -1 is out of range for type 'fb_info *[32]' ... fbcon_info_from_console+0x192/0x1a0 drivers/video/fbdev/core/fbcon.c:122 fbcon_new_modelist+0xbf/0x2d0 drivers/video/fbdev/core/fbcon.c:3048 fb_new_modelist+0x328/0x440 drivers/video/fbdev/core/fbmem.c:673 store_modes+0x1c9/0x3e0 drivers/video/fbdev/core/fbsysfs.c:113 dev_attr_store+0x55/0x80 drivers/base/core.c:2439 static struct fb_info *fbcon_registered_fb[FB_MAX]; ... static signed char con2fb_map[MAX_NR_CONSOLES]; ... static struct fb_info *fbcon_info_from_console(int console) ... return fbcon_registered_fb[con2fb_map[console]]; If con2fb_map contains a -1 things go wrong here. Instead, return NULL, as callers of fbcon_info_from_console() are trying to compare against existing "info" pointers, so error handling should kick in correctly. Reported-by: syzbot+a7d4444e7b6e743572f7(a)syzkaller.appspotmail.com Closes: https://lore.kernel.org/all/679d0a8f.050a0220.163cdc.000c.GAE@google.com/ Signed-off-by: Kees Cook <kees(a)kernel.org> Signed-off-by: Helge Deller <deller(a)gmx.de> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- **YES** This commit should be backported to stable kernel trees. Here's my analysis: ## Security and Stability Issue This commit fixes a critical **array-index-out-of-bounds vulnerability** that can be triggered via sysfs. The issue occurs when `con2fb_map[console]` contains `-1`, causing `fbcon_info_from_console()` to access `fbcon_registered_fb[-1]`, which is an out-of-bounds array access. ## Bug Analysis The problem is in the `fbcon_info_from_console()` function at line 122: ```c // Before fix: return fbcon_registered_fb[con2fb_map[console]]; // After fix: fb = con2fb_map[console]; if (fb < 0 || fb >= ARRAY_SIZE(fbcon_registered_fb)) return NULL; return fbcon_registered_fb[fb]; ``` ## Trigger Path The vulnerability can be triggered through: 1. **sysfs interface**: Writing to `/sys/class/graphics/fbX/modes` 2. **Call chain**: `store_modes()` → `fb_new_modelist()` → `fbcon_new_modelist()` → `fbcon_info_from_console()` 3. **User-accessible**: This is exploitable from userspace through the sysfs interface ## Code Context from Analysis Based on the git blame, the vulnerable code path in `fbcon_new_modelist()` has existed since: - Original code from **2005** (Linus Torvalds) - The problematic `fbcon_info_from_console()` call was added in **2022** by commit `409d6c95f9c6` ("fbcon: Introduce wrapper for console->fb_info lookup") ## Risk Assessment 1. **High Impact**: UBSAN array bounds violation, potential for memory corruption 2. **User Triggerable**: Accessible via standard sysfs interface 3. **Long- standing**: The vulnerable pattern has existed since 2022 when the wrapper was introduced 4. **Active Exploitation**: Reported by syzbot, indicating active fuzzing found this issue ## Backport Suitability 1. **Small & Contained**: Only 6 lines changed in a single function 2. **Safe Fix**: Adds bounds checking without changing logic flow 3. **No Dependencies**: The fix is self-contained and doesn't require other commits 4. **Clear Bug**: Definitively fixes out-of-bounds access with proper NULL return 5. **Stable Pattern**: Callers already handle NULL returns from `fbcon_info_from_console()` ## Comparison to Historical Precedent Looking at the similar commits provided: - **Similar Commit #1** (Backport Status: YES): Fixed boundary checks in fbcon parameter parsing - this follows the same pattern of fixing bounds issues in fbcon - The other NO commits were architectural changes or refactoring, not security fixes This commit perfectly fits the stable tree criteria: it's an important bugfix, has minimal regression risk, is contained to a single subsystem, and fixes a user-triggerable vulnerability. drivers/video/fbdev/core/fbcon.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/drivers/video/fbdev/core/fbcon.c b/drivers/video/fbdev/core/fbcon.c index ac3c99ed92d1a..2df48037688d1 100644 --- a/drivers/video/fbdev/core/fbcon.c +++ b/drivers/video/fbdev/core/fbcon.c @@ -117,9 +117,14 @@ static signed char con2fb_map_boot[MAX_NR_CONSOLES]; static struct fb_info *fbcon_info_from_console(int console) { + signed char fb; WARN_CONSOLE_UNLOCKED(); - return fbcon_registered_fb[con2fb_map[console]]; + fb = con2fb_map[console]; + if (fb < 0 || fb >= ARRAY_SIZE(fbcon_registered_fb)) + return NULL; + + return fbcon_registered_fb[fb]; } static int logo_lines; -- 2.39.5

[PATCH AUTOSEL 5.4 1/5] watchdog: da9052_wdt: respect TWDMIN

by Sasha Levin

From: Marcus Folkesson <marcus.folkesson(a)gmail.com> [ Upstream commit 325f510fcd9cda5a44bcb662b74ba4e3dabaca10 ] We have to wait at least the minimium time for the watchdog window (TWDMIN) before writings to the wdt register after the watchdog is activated.

[PATCH AUTOSEL 6.1 1/6] fbcon: Make sure modelist not set on unregistered console

by Sasha Levin

From: Kees Cook <kees(a)kernel.org> [ Upstream commit cedc1b63394a866bf8663a3e40f4546f1d28c8d8 ] It looks like attempting to write to the "store_modes" sysfs node will run afoul of unregistered consoles: UBSAN: array-index-out-of-bounds in drivers/video/fbdev/core/fbcon.c:122:28 index -1 is out of range for type 'fb_info *[32]' ... fbcon_info_from_console+0x192/0x1a0 drivers/video/fbdev/core/fbcon.c:122 fbcon_new_modelist+0xbf/0x2d0 drivers/video/fbdev/core/fbcon.c:3048 fb_new_modelist+0x328/0x440 drivers/video/fbdev/core/fbmem.c:673 store_modes+0x1c9/0x3e0 drivers/video/fbdev/core/fbsysfs.c:113 dev_attr_store+0x55/0x80 drivers/base/core.c:2439 static struct fb_info *fbcon_registered_fb[FB_MAX]; ... static signed char con2fb_map[MAX_NR_CONSOLES]; ... static struct fb_info *fbcon_info_from_console(int console) ... return fbcon_registered_fb[con2fb_map[console]]; If con2fb_map contains a -1 things go wrong here. Instead, return NULL, as callers of fbcon_info_from_console() are trying to compare against existing "info" pointers, so error handling should kick in correctly. Reported-by: syzbot+a7d4444e7b6e743572f7(a)syzkaller.appspotmail.com Closes: https://lore.kernel.org/all/679d0a8f.050a0220.163cdc.000c.GAE@google.com/ Signed-off-by: Kees Cook <kees(a)kernel.org> Signed-off-by: Helge Deller <deller(a)gmx.de> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- **YES** This commit should be backported to stable kernel trees. Here's my analysis: ## Security and Stability Issue This commit fixes a critical **array-index-out-of-bounds vulnerability** that can be triggered via sysfs. The issue occurs when `con2fb_map[console]` contains `-1`, causing `fbcon_info_from_console()` to access `fbcon_registered_fb[-1]`, which is an out-of-bounds array access. ## Bug Analysis The problem is in the `fbcon_info_from_console()` function at line 122: ```c // Before fix: return fbcon_registered_fb[con2fb_map[console]]; // After fix: fb = con2fb_map[console]; if (fb < 0 || fb >= ARRAY_SIZE(fbcon_registered_fb)) return NULL; return fbcon_registered_fb[fb]; ``` ## Trigger Path The vulnerability can be triggered through: 1. **sysfs interface**: Writing to `/sys/class/graphics/fbX/modes` 2. **Call chain**: `store_modes()` → `fb_new_modelist()` → `fbcon_new_modelist()` → `fbcon_info_from_console()` 3. **User-accessible**: This is exploitable from userspace through the sysfs interface ## Code Context from Analysis Based on the git blame, the vulnerable code path in `fbcon_new_modelist()` has existed since: - Original code from **2005** (Linus Torvalds) - The problematic `fbcon_info_from_console()` call was added in **2022** by commit `409d6c95f9c6` ("fbcon: Introduce wrapper for console->fb_info lookup") ## Risk Assessment 1. **High Impact**: UBSAN array bounds violation, potential for memory corruption 2. **User Triggerable**: Accessible via standard sysfs interface 3. **Long- standing**: The vulnerable pattern has existed since 2022 when the wrapper was introduced 4. **Active Exploitation**: Reported by syzbot, indicating active fuzzing found this issue ## Backport Suitability 1. **Small & Contained**: Only 6 lines changed in a single function 2. **Safe Fix**: Adds bounds checking without changing logic flow 3. **No Dependencies**: The fix is self-contained and doesn't require other commits 4. **Clear Bug**: Definitively fixes out-of-bounds access with proper NULL return 5. **Stable Pattern**: Callers already handle NULL returns from `fbcon_info_from_console()` ## Comparison to Historical Precedent Looking at the similar commits provided: - **Similar Commit #1** (Backport Status: YES): Fixed boundary checks in fbcon parameter parsing - this follows the same pattern of fixing bounds issues in fbcon - The other NO commits were architectural changes or refactoring, not security fixes This commit perfectly fits the stable tree criteria: it's an important bugfix, has minimal regression risk, is contained to a single subsystem, and fixes a user-triggerable vulnerability. drivers/video/fbdev/core/fbcon.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/drivers/video/fbdev/core/fbcon.c b/drivers/video/fbdev/core/fbcon.c index e6640edec155e..030ba5b808dfe 100644 --- a/drivers/video/fbdev/core/fbcon.c +++ b/drivers/video/fbdev/core/fbcon.c @@ -115,9 +115,14 @@ static signed char con2fb_map_boot[MAX_NR_CONSOLES]; static struct fb_info *fbcon_info_from_console(int console) { + signed char fb; WARN_CONSOLE_UNLOCKED(); - return fbcon_registered_fb[con2fb_map[console]]; + fb = con2fb_map[console]; + if (fb < 0 || fb >= ARRAY_SIZE(fbcon_registered_fb)) + return NULL; + + return fbcon_registered_fb[fb]; } static int logo_lines; -- 2.39.5
