In the Linux kernel, the following vulnerability has been resolved: tools/nolibc/stdlib: fix memory error in realloc() Pass user_p_len to memcpy() instead of heap->len to prevent realloc() from copying an extra sizeof(heap) bytes from beyond the allocated region. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tools/nolibc/stdlib: corrige el error de memoria en realloc() Pase user_p_len a memcpy() en lugar de heap->len para evitar que realloc() copie un tamaño extra de(heap) bytes más allá de la región asignada. • https://git.kernel.org/stable/c/0e0ff638400be8f497a35b51a4751fd823f6bd6a https://git.kernel.org/stable/c/5996b2b2dac739f2a27da13de8eee5b85b2550b3 https://git.kernel.org/stable/c/f678c3c336559cf3255a32153e9a17c1be4e7c15 https://git.kernel.org/stable/c/8019d3dd921f39a237a9fab6d2ce716bfac0f983 https://git.kernel.org/stable/c/4e6f225aefeb712cdb870176b6621f02cf235b8c https://git.kernel.org/stable/c/791f4641142e2aced85de082e5783b4fb0b977c2 •

In the Linux kernel, the following vulnerability has been resolved: net: ti: icssg_prueth: Fix NULL pointer dereference in prueth_probe() In the prueth_probe() function, if one of the calls to emac_phy_connect() fails due to of_phy_connect() returning NULL, then the subsequent call to phy_attached_info() will dereference a NULL pointer. Check the return code of emac_phy_connect and fail cleanly if there is an error. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: ti: icssg_prueth: corrige la desreferencia del puntero NULL en prueth_probe() En la función prueth_probe(), si una de las llamadas a emac_phy_connect() falla debido a que of_phy_connect() devuelve NULL , entonces la llamada posterior a phy_attached_info() eliminará la referencia a un puntero NULL.

CVSS: -EPSS: 0%CPEs: 9EXPL: 0CVE-2024-38583 – nilfs2: fix use-after-free of timer for log writer thread
https://notcve.org/view.php?id=CVE-2024-38583
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix use-after-free of timer for log writer thread Patch series "nilfs2: fix log writer related issues". This bug fix series covers three nilfs2 log writer-related issues, including a timer use-after-free issue and potential deadlock issue on unmount, and a potential freeze issue in event synchronization found during their analysis. Details are described in each commit log. This patch (of 3): A use-after-free issue has been reported regarding the timer sc_timer on the nilfs_sc_info structure. The problem is that even though it is used to wake up a sleeping log writer thread, sc_timer is not shut down until the nilfs_sc_info structure is about to be freed, and is used regardless of the thread's lifetime. Fix this issue by limiting the use of sc_timer only while the log writer thread is alive. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nilfs2: corrige el use-after-free del temporizador para el hilo del escritor de registros Serie de parches "nilfs2: corrige problemas relacionados con el escritor de registros". Esta serie de corrección de errores cubre tres problemas relacionados con el escritor de registros nilfs2, incluido un problema de use-after-free del temporizador y un posible problema de bloqueo al desmontar, y un posible problema de congelación en la sincronización de eventos encontrado durante su análisis. Los detalles se describen en cada registro de confirmación. • https://git.kernel.org/stable/c/fdce895ea5dd4e24edf1f4d693827349a4e5b3b4 https://git.kernel.org/stable/c/822ae5a8eac30478578a75f7e064f0584931bf2d https://git.kernel.org/stable/c/82933c84f188dcfe89eb26b0b48ab5d1ca99d164 https://git.kernel.org/stable/c/67fa90d4a2ccd9ebb0e1e168c7d0b5d0cf3c7148 https://git.kernel.org/stable/c/e65ccf3a4de4f0c763d94789615b83e11f204438 https://git.kernel.org/stable/c/86a30d6302deddb9fb97ba6fc4b04d0e870b582a https://git.kernel.org/stable/c/f9186bba4ea282b07293c1c892441df3a5441cb0 https://git.kernel.org/stable/c/2f12b2c03c5dae1a0de0a9e5853177e3d •
CVSS: -EPSS: 0%CPEs: 9EXPL: 0CVE-2024-38582 – nilfs2: fix potential hang in nilfs_detach_log_writer()
https://notcve.org/view.php?id=CVE-2024-38582
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix potential hang in nilfs_detach_log_writer() Syzbot has reported a potential hang in nilfs_detach_log_writer() called during nilfs2 unmount. Analysis revealed that this is because nilfs_segctor_sync(), which synchronizes with the log writer thread, can be called after nilfs_segctor_destroy() terminates that thread, as shown in the call trace below: nilfs_detach_log_writer nilfs_segctor_destroy nilfs_segctor_kill_thread --> Shut down log writer thread flush_work nilfs_iput_work_func nilfs_dispose_list iput nilfs_evict_inode nilfs_transaction_commit nilfs_construct_segment (if inode needs sync) nilfs_segctor_sync --> Attempt to synchronize with log writer thread *** DEADLOCK *** Fix this issue by changing nilfs_segctor_sync() so that the log writer thread returns normally without synchronizing after it terminates, and by forcing tasks that are already waiting to complete once after the thread terminates. The skipped inode metadata flushout will then be processed together in the subsequent cleanup work in nilfs_segctor_destroy(). En el kernel de Linux, se resolvió la siguiente vulnerabilidad: nilfs2: soluciona un posible bloqueo en nilfs_detach_log_writer() Syzbot ha informado de un posible bloqueo en nilfs_detach_log_writer() llamado durante el desmontaje de nilfs2. El análisis reveló que esto se debe a que nilfs_segctor_sync(), que se sincroniza con el hilo del escritor de registros, puede ser llamado después de que nilfs_segctor_destroy() finalice ese hilo, como se muestra en el seguimiento de llamadas a continuación: nilfs_detach_log_writer nilfs_segctor_destroy nilfs_segctor_kill_thread --> Apagar el hilo del escritor de registros Flush_work nilfs_iput_work_func nilfs_dispose_list iput nilfs_evict_inode nilfs_transaction_commit nilfs_construct_segment (si el inodo necesita sincronización) nilfs_segctor_sync --> Intente sincronizar con el hilo del escritor de registros *** DEADLOCK *** Solucione este problema cambiando nilfs_segctor_sync() para que el hilo del escritor de registros regrese normalmente sin sincronizarse después de que termine y forzando las tareas que ya están esperando a completarse una vez que finaliza el hilo. La eliminación de metadatos del inodo omitido se procesará en conjunto en el trabajo de limpieza posterior en nilfs_segctor_destroy(). • https://git.kernel.org/stable/c/911d38be151921a5d152bb55e81fd752384c6830 https://git.kernel.org/stable/c/bc9cee50a4a4ca23bdc49f75ea8242d8a2193b3b https://git.kernel.org/stable/c/eff7cdf890b02596b8d73e910bdbdd489175dbdb https://git.kernel.org/stable/c/06afce714d87c7cd1dcfccbcd800c5c5d2cf1cfd https://git.kernel.org/stable/c/1c3844c5f4eac043954ebf6403fa9fd1f0e9c1c0 https://git.kernel.org/stable/c/a8799662fed1f8747edae87a1937549288baca6a https://git.kernel.org/stable/c/6e5c8e8e024e147b834f56f2115aad241433679b https://git.kernel.org/stable/c/c516db6ab9eabbedbc430b4f93b0d8728 •
