https://notcve.org/view.php?id=CVE-2024-26763
In the Linux kernel, the following vulnerability has been resolved: dm-crypt: don't modify the data when using authenticated encryption It was said that authenticated encryption could produce invalid tag when the data that is being encrypted is modified [1]. So, fix this problem by copying the data into the clone bio first and then encrypt them inside the clone bio. This may reduce performance, but it is needed to prevent the user from corrupting the device by writing data with O_DIRECT and modifying them at the same time. [1] https://lore.kernel.org/all/20240207004723.GA35324@sol.localdomain/T/ En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: dm-crypt: no modifica los datos cuando se utiliza cifrado autenticado Se dijo que el cifrado autenticado podría producir etiquetas no válidas cuando se modifican los datos que se están cifrando [1]. Entonces, solucione este problema copiando primero los datos en la biografía del clon y luego cifrándolos dentro de la biografía del clon. Esto puede reducir el rendimiento, pero es necesario para evitar que el usuario dañe el dispositivo escribiendo datos con O_DIRECT y modificándolos al mismo tiempo.

https://notcve.org/view.php?id=CVE-2024-26759
In the Linux kernel, the following vulnerability has been resolved: mm/swap: fix race when skipping swapcache When skipping swapcache for SWP_SYNCHRONOUS_IO, if two or more threads swapin the same entry at the same time, they get different pages (A, B). Before one thread (T0) finishes the swapin and installs page (A) to the PTE, another thread (T1) could finish swapin of page (B), swap_free the entry, then swap out the possibly modified page reusing the same entry. It breaks the pte_same check in (T0) because PTE value is unchanged, causing ABA problem. Thread (T0) will install a stalled page (A) into the PTE and cause data corruption. One possible callstack is like this: CPU0 CPU1 ---- ---- do_swap_page() do_swap_page() with same entry <direct swapin path> <direct swapin path> <alloc page A> <alloc page B> swap_read_folio() <- read to page A swap_read_folio() <- read to page B <slow on later locks or interrupt> <finished swapin first> ... set_pte_at() swap_free() <- entry is free <write to page B, now page A stalled> <swap out page B to same swap entry> pte_same() <- Check pass, PTE seems unchanged, but page A is stalled! swap_free() <- page B content lost! set_pte_at() <- staled page A installed! • https://git.kernel.org/stable/c/0bcac06f27d7528591c27ac2b093ccd71c5d0168 https://git.kernel.org/stable/c/2dedda77d4493f3e92e414b272bfa60f1f51ed95 https://git.kernel.org/stable/c/305152314df82b22cf9b181f3dc5fc411002079a https://git.kernel.org/stable/c/d183a4631acfc7af955c02a02e739cec15f5234d https://git.kernel.org/stable/c/13ddaf26be324a7f951891ecd9ccd04466d27458 https://access.redhat.com/security/cve/CVE-2024-26759 https://bugzilla.redhat.com/show_bug.cgi?id=2273204 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

In the Linux kernel, the following vulnerability has been resolved: md: Don't ignore suspended array in md_check_recovery() mddev_suspend() never stop sync_thread, hence it doesn't make sense to ignore suspended array in md_check_recovery(), which might cause sync_thread can't be unregistered. After commit f52f5c71f3d4 ("md: fix stopping sync thread"), following hang can be triggered by test shell/integrity-caching.sh: 1) suspend the array: raid_postsuspend mddev_suspend 2) stop the array: raid_dtr md_stop __md_stop_writes stop_sync_thread set_bit(MD_RECOVERY_INTR, &mddev->recovery); md_wakeup_thread_directly(mddev->sync_thread); wait_event(..., !test_bit(MD_RECOVERY_RUNNING, &mddev->recovery)) 3) sync thread done: md_do_sync set_bit(MD_RECOVERY_DONE, &mddev->recovery); md_wakeup_thread(mddev->thread); 4) daemon thread can't unregister sync thread: md_check_recovery if (mddev->suspended) return; -> return directly md_read_sync_thread clear_bit(MD_RECOVERY_RUNNING, &mddev->recovery); -> MD_RECOVERY_RUNNING can't be cleared, hence step 2 hang; This problem is not just related to dm-raid, fix it by ignoring suspended array in md_check_recovery(). And follow up patches will improve dm-raid better to frozen sync thread during suspend. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: md: No ignorar la matriz suspendida en md_check_recovery() mddev_suspend() nunca detiene sync_thread, por lo tanto, no tiene sentido ignorar la matriz suspendida en md_check_recovery(), lo que podría causar sync_thread no se puede cancelar el registro.
