https://notcve.org/view.php?id=CVE-2023-52669
In the Linux kernel, the following vulnerability has been resolved: crypto: s390/aes - Fix buffer overread in CTR mode When processing the last block, the s390 ctr code will always read a whole block, even if there isn't a whole block of data left. Fix this by using the actual length left and copy it into a buffer first for processing. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: crypto: s390/aes - Corrige la sobrelectura del buffer en modo CTR Al procesar el último bloque, el código ctr s390 siempre leerá un bloque completo, incluso si no hay un bloque completo de datos restantes. Solucione este problema utilizando la longitud real restante y cópielo primero en un búfer para procesarlo. • https://git.kernel.org/stable/c/0200f3ecc19660bebeabbcbaf212957fcf1dbf8f https://git.kernel.org/stable/c/cd51e26a3b89706beec64f2d8296cfb1c34e0c79 https://git.kernel.org/stable/c/a7f580cdb42ec3d53bbb7c4e4335a98423703285 https://git.kernel.org/stable/c/dbc9a791a70ea47be9f2acf251700fe254a2ab23 https://git.kernel.org/stable/c/d68ac38895e84446848b7647ab9458d54cacba3e https://git.kernel.org/stable/c/e78f1a43e72daf77705ad5b9946de66fc708b874 https://git.kernel.org/stable/c/d07f951903fa9922c375b8ab1ce81b18a0034e3b https://lists.debian.org/debian-lts-announce/2024/06/ •

https://notcve.org/view.php?id=CVE-2023-52668
In the Linux kernel, the following vulnerability has been resolved: btrfs: zoned: fix lock ordering in btrfs_zone_activate() The btrfs CI reported a lockdep warning as follows by running generic generic/129. WARNING: possible circular locking dependency detected 6.7.0-rc5+ #1 Not tainted ------------------------------------------------------ kworker/u5:5/793427 is trying to acquire lock: ffff88813256d028 (&cache->lock){+.+.}-{2:2}, at: btrfs_zone_finish_one_bg+0x5e/0x130 but task is already holding lock: ffff88810a23a318 (&fs_info->zone_active_bgs_lock){+.+.}-{2:2}, at: btrfs_zone_finish_one_bg+0x34/0x130 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (&fs_info->zone_active_bgs_lock){+.+.}-{2:2}: ... -> #0 (&cache->lock){+.+.}-{2:2}: ... This is because we take fs_info->zone_active_bgs_lock after a block_group's lock in btrfs_zone_activate() while doing the opposite in other places. Fix the issue by expanding the fs_info->zone_active_bgs_lock's critical section and taking it before a block_group's lock. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: btrfs:zoned: corrige el orden de bloqueo en btrfs_zone_activate() El CI de btrfs informó una advertencia de bloqueo de la siguiente manera al ejecutar generic generic/129.

CVSS: 4.7EPSS: 0%CPEs: 5EXPL: 0CVE-2023-52667 – net/mlx5e: fix a potential double-free in fs_any_create_groups
https://notcve.org/view.php?id=CVE-2023-52667
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: fix a potential double-free in fs_any_create_groups When kcalloc() for ft->g succeeds but kvzalloc() for in fails, fs_any_create_groups() will free ft->g. However, its caller fs_any_create_table() will free ft->g again through calling mlx5e_destroy_flow_table(), which will lead to a double-free. Fix this by setting ft->g to NULL in fs_any_create_groups(). En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/mlx5e: corrige una posible double free en fs_any_create_groups Cuando kcalloc() para ft->g tiene éxito pero kvzalloc() para in falla, fs_any_create_groups() liberará ft-> gramo. Sin embargo, su llamador fs_any_create_table() liberará ft->g nuevamente llamando a mlx5e_destroy_flow_table(), lo que conducirá a un double free. Solucione este problema configurando ft->g en NULL en fs_any_create_groups(). • https://git.kernel.org/stable/c/0f575c20bf0686caf3d82d6c626c2e1e4a4c36e6 https://git.kernel.org/stable/c/72a729868592752b5a294d27453da264106983b1 https://git.kernel.org/stable/c/b2fa86b2aceb4bc9ada51cea90f61546d7512cbe https://git.kernel.org/stable/c/2897c981ee63e1be5e530b1042484626a10b26d8 https://git.kernel.org/stable/c/65a4ade8a6d205979292e88beeb6a626ddbd4779 https://git.kernel.org/stable/c/aef855df7e1bbd5aa4484851561211500b22707e https://access.redhat.com/security/cve/CVE-2023-52667 https://bugzilla.redhat.com/show_bug.cgi?id=2281350 • CWE-415: Double Free •
