https://notcve.org/view.php?id=CVE-2024-49961
In the Linux kernel, the following vulnerability has been resolved: media: i2c: ar0521: Use cansleep version of gpiod_set_value() If we use GPIO reset from I2C port expander, we must use *_cansleep() variant of GPIO functions. This was not done in ar0521_power_on()/ar0521_power_off() functions. Let's fix that. ------------[ cut here ]------------ WARNING: CPU: 0 PID: 11 at drivers/gpio/gpiolib.c:3496 gpiod_set_value+0x74/0x7c Modules linked in: CPU: 0 PID: 11 Comm: kworker/u16:0 Not tainted 6.10.0 #53 Hardware name: Diasom DS-RK3568-SOM-EVB (DT) Workqueue: events_unbound deferred_probe_work_func pstate: 80400009 (Nzcv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : gpiod_set_value+0x74/0x7c lr : ar0521_power_on+0xcc/0x290 sp : ffffff8001d7ab70 x29: ffffff8001d7ab70 x28: ffffff80027dcc90 x27: ffffff8003c82000 x26: ffffff8003ca9250 x25: ffffffc080a39c60 x24: ffffff8003ca9088 x23: ffffff8002402720 x22: ffffff8003ca9080 x21: ffffff8003ca9088 x20: 0000000000000000 x19: ffffff8001eb2a00 x18: ffffff80efeeac80 x17: 756d2d6332692f30 x16: 0000000000000000 x15: 0000000000000000 x14: ffffff8001d91d40 x13: 0000000000000016 x12: ffffffc080e98930 x11: ffffff8001eb2880 x10: 0000000000000890 x9 : ffffff8001d7a9f0 x8 : ffffff8001d92570 x7 : ffffff80efeeac80 x6 : 000000003fc6e780 x5 : ffffff8001d91c80 x4 : 0000000000000002 x3 : 0000000000000000 x2 : 0000000000000000 x1 : 0000000000000000 x0 : 0000000000000001 Call trace: gpiod_set_value+0x74/0x7c ar0521_power_on+0xcc/0x290 ... • https://git.kernel.org/stable/c/852b50aeed153b513c0b36298559114fab0fab80 https://git.kernel.org/stable/c/9f08876d766755a92f1b9543ae3ee21bfc596fb8 https://git.kernel.org/stable/c/625a77b68c96349c16fcc1faa42784313e0b1a85 https://git.kernel.org/stable/c/2423b60a2d6d27e5f66c5021b494463aef2db212 https://git.kernel.org/stable/c/3cf00ecfbf11ee8e6afff306a5bdcff4bf95d2cf https://git.kernel.org/stable/c/bee1aed819a8cda47927436685d216906ed17f62 •

https://notcve.org/view.php?id=CVE-2024-49960
In the Linux kernel, the following vulnerability has been resolved: ext4: fix timer use-after-free on failed mount Syzbot has found an ODEBUG bug in ext4_fill_super The del_timer_sync function cancels the s_err_report timer, which reminds about filesystem errors daily. We should guarantee the timer is no longer active before kfree(sbi). When filesystem mounting fails, the flow goes to failed_mount3, where an error occurs when ext4_stop_mmpd is called, causing a read I/O failure. This triggers the ext4_handle_error function that ultimately re-arms the timer, leaving the s_err_report timer active before kfree(sbi) is called. Fix the issue by canceling the s_err_report timer after calling ext4_stop_mmpd. • https://git.kernel.org/stable/c/9203817ba46ebba7c865c8de2aba399537b6e891 https://git.kernel.org/stable/c/fa78fb51d396f4f2f80f8e96a3b1516f394258be https://git.kernel.org/stable/c/b85569585d0154d4db1e4f9e3e6a4731d407feb0 https://git.kernel.org/stable/c/0ce160c5bdb67081a62293028dc85758a8efb22a •

In the Linux kernel, the following vulnerability has been resolved: jbd2: stop waiting for space when jbd2_cleanup_journal_tail() returns error In __jbd2_log_wait_for_space(), we might call jbd2_cleanup_journal_tail() to recover some journal space.

In the Linux kernel, the following vulnerability has been resolved: ocfs2: reserve space for inline xattr before attaching reflink tree One of our customers reported a crash and a corrupted ocfs2 filesystem.

CVSS: -EPSS: 0%CPEs: 9EXPL: 0CVE-2024-49957 – ocfs2: fix null-ptr-deref when journal load failed.
https://notcve.org/view.php?id=CVE-2024-49957
In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix null-ptr-deref when journal load failed. During the mounting process, if journal_reset() fails because of too short journal, then lead to jbd2_journal_load() fails with NULL j_sb_buffer. Subsequently, ocfs2_journal_shutdown() calls jbd2_journal_flush()->jbd2_cleanup_journal_tail()-> __jbd2_update_log_tail()->jbd2_journal_update_sb_log_tail() ->lock_buffer(journal->j_sb_buffer), resulting in a null-pointer dereference error. To resolve this issue, we should check the JBD2_LOADED flag to ensure the journal was properly loaded. Additionally, use journal instead of osb->journal directly to simplify the code. • https://git.kernel.org/stable/c/f6f50e28f0cb8d7bcdfaacc83129f005dede11b1 https://git.kernel.org/stable/c/fd89d92c1140cee8f59de336cb37fa65e359c123 https://git.kernel.org/stable/c/703b2c7e0798d263154dc8593dc2345f75dc077f https://git.kernel.org/stable/c/bf605ae98dab5c15c5b631d4d7f88898cb41b649 https://git.kernel.org/stable/c/ff55291fb36779819211b596da703389135f5b05 https://git.kernel.org/stable/c/82dfdd1e31e774578f76ce6dc90c834f96403a0f https://git.kernel.org/stable/c/86a89e75e9e4dfa768b97db466ad6bedf2e7ea5b https://git.kernel.org/stable/c/f60e94a83db799bde625ac8671a5b4a63 •
