https://notcve.org/view.php?id=CVE-2024-26726
In the Linux kernel, the following vulnerability has been resolved: btrfs: don't drop extent_map for free space inode on write error While running the CI for an unrelated change I hit the following panic with generic/648 on btrfs_holes_spacecache. assertion failed: block_start != EXTENT_MAP_HOLE, in fs/btrfs/extent_io.c:1385 ------------[ cut here ]------------ kernel BUG at fs/btrfs/extent_io.c:1385! invalid opcode: 0000 [#1] PREEMPT SMP NOPTI CPU: 1 PID: 2695096 Comm: fsstress Kdump: loaded Tainted: G W 6.8.0-rc2+ #1 RIP: 0010:__extent_writepage_io.constprop.0+0x4c1/0x5c0 Call Trace: <TASK> extent_write_cache_pages+0x2ac/0x8f0 extent_writepages+0x87/0x110 do_writepages+0xd5/0x1f0 filemap_fdatawrite_wbc+0x63/0x90 __filemap_fdatawrite_range+0x5c/0x80 btrfs_fdatawrite_range+0x1f/0x50 btrfs_write_out_cache+0x507/0x560 btrfs_write_dirty_block_groups+0x32a/0x420 commit_cowonly_roots+0x21b/0x290 btrfs_commit_transaction+0x813/0x1360 btrfs_sync_file+0x51a/0x640 __x64_sys_fdatasync+0x52/0x90 do_syscall_64+0x9c/0x190 entry_SYSCALL_64_after_hwframe+0x6e/0x76 This happens because we fail to write out the free space cache in one instance, come back around and attempt to write it again. However on the second pass through we go to call btrfs_get_extent() on the inode to get the extent mapping. Because this is a new block group, and with the free space inode we always search the commit root to avoid deadlocking with the tree, we find nothing and return a EXTENT_MAP_HOLE for the requested range. This happens because the first time we try to write the space cache out we hit an error, and on an error we drop the extent mapping. • https://git.kernel.org/stable/c/02f2b95b00bf57d20320ee168b30fb7f3db8e555 https://git.kernel.org/stable/c/7bddf18f474f166c19f91b2baf67bf7c5eda03f7 https://git.kernel.org/stable/c/a4b7741c8302e28073bfc6dd1c2e73598e5e535e https://git.kernel.org/stable/c/5571e41ec6e56e35f34ae9f5b3a335ef510e0ade •

In the Linux kernel, the following vulnerability has been resolved: ASoC: rt5645: Fix deadlock in rt5645_jack_detect_work() There is a path in rt5645_jack_detect_work(), where rt5645->jd_mutex is left locked forever. That may lead to deadlock when rt5645_jack_detect_work() is called for the second time. Found by Linux Verification Center (linuxtesting.org) with SVACE. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ASoC: rt5645: corrige el punto muerto en rt5645_jack_detect_work() Hay una ruta en rt5645_jack_detect_work(), donde rt5645->jd_mutex queda bloqueado para siempre.

CVSS: 5.5EPSS: 0%CPEs: 18EXPL: 0CVE-2024-26720 – mm/writeback: fix possible divide-by-zero in wb_dirty_limits(), again
https://notcve.org/view.php?id=CVE-2024-26720
In the Linux kernel, the following vulnerability has been resolved: mm/writeback: fix possible divide-by-zero in wb_dirty_limits(), again (struct dirty_throttle_control *)->thresh is an unsigned long, but is passed as the u32 divisor argument to div_u64(). On architectures where unsigned long is 64 bytes, the argument will be implicitly truncated. Use div64_u64() instead of div_u64() so that the value used in the "is this a safe division" check is the same as the divisor. Also, remove redundant cast of the numerator to u64, as that should happen implicitly. This would be difficult to exploit in memcg domain, given the ratio-based arithmetic domain_drity_limits() uses, but is much easier in global writeback domain with a BDI_CAP_STRICTLIMIT-backing device, using e.g. vm.dirty_bytes=(1<<32)*PAGE_SIZE so that dtc->thresh == (1<<32) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: mm/writeback: corrige la posible división por cero en wb_dirty_limits(), nuevamente (struct dirty_throttle_control *)->thresh es un largo sin firmar, pero se pasa como argumento del divisor u32 a div_u64(). En arquitecturas donde la longitud sin firmar es de 64 bytes, el argumento se truncará implícitamente. Utilice div64_u64() en lugar de div_u64() para que el valor utilizado en la comprobación "¿Es esta una división segura" sea el mismo que el divisor? Además, elimine la conversión redundante del numerador a u64, ya que eso debería suceder implícitamente. • https://git.kernel.org/stable/c/f6789593d5cea42a4ecb1cbeab6a23ade5ebbba7 https://git.kernel.org/stable/c/c5fec566bef6a027e75c84c35ec970482eb88cea https://git.kernel.org/stable/c/c05d1fe6c19f4df2f0b8cba151a8f0c53b87d878 https://git.kernel.org/stable/c/3f7d325fbbe12e5ade71a1f90759c06ed2d27e3c https://git.kernel.org/stable/c/c593d26fb5d577ef31b6e49a31e08ae3ebc1bc1e https://git.kernel.org/stable/c/253f9ea7e8e53a5176bd80ceb174907b10724c1a https://git.kernel.org/stable/c/1f12e4b3284d6c863f272eb2de0d4248ed211cf4 https://git.kernel.org/stable/c/23a28f5f3f6ca1e4184bd0e9631cd0944 • CWE-369: Divide By Zero •
