In the Linux kernel, the following vulnerability has been resolved: iio: magnetometer: rm3100: add boundary check for the value read from RM3100_REG_TMRC Recently, we encounter kernel crash in function rm3100_common_probe caused by out of bound access of array rm3100_samp_rates (because of underlying hardware failures). Add boundary check to prevent out of bound access. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: iio: magnetómetro: rm3100: agregue verificación de los límites para el valor leído de RM3100_REG_TMRC Recientemente, encontramos una falla del kernel en la función rm3100_common_probe causada por el acceso fuera de los límites de la matriz rm3100_samp_rates (debido al hardware subyacente fallas).

https://notcve.org/view.php?id=CVE-2024-26697
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix data corruption in dsync block recovery for small block sizes The helper function nilfs_recovery_copy_block() of nilfs_recovery_dsync_blocks(), which recovers data from logs created by data sync writes during a mount after an unclean shutdown, incorrectly calculates the on-page offset when copying repair data to the file's page cache. In environments where the block size is smaller than the page size, this flaw can cause data corruption and leak uninitialized memory bytes during the recovery process. Fix these issues by correcting this byte offset calculation on the page. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: nilfs2: corrige la corrupción de datos en la recuperación de bloques dsync para tamaños de bloques pequeños La función auxiliar nilfs_recovery_copy_block() de nilfs_recovery_dsync_blocks(), que recupera datos de los registros creados por escrituras de sincronización de datos durante un montaje después un apagado incorrecto calcula incorrectamente el desplazamiento en la página al copiar los datos de reparación en la memoria caché de la página del archivo. En entornos donde el tamaño del bloque es menor que el tamaño de la página, esta falla puede causar corrupción de datos y pérdida de bytes de memoria no inicializados durante el proceso de recuperación. Solucione estos problemas corrigiendo este cálculo de desplazamiento de bytes en la página. • https://git.kernel.org/stable/c/5278c3eb6bf5896417572b52adb6be9d26e92f65 https://git.kernel.org/stable/c/a6efe6dbaaf504f5b3f8a5c3f711fe54e7dda0ba https://git.kernel.org/stable/c/364a66be2abdcd4fd426ffa44d9b8f40aafb3caa https://git.kernel.org/stable/c/120f7fa2008e3bd8b7680b4ab5df942decf60fd5 https://git.kernel.org/stable/c/9c9c68d64fd3284f7097ed6ae057c8441f39fcd3 https://git.kernel.org/stable/c/2e1480538ef60bfee5473dfe02b1ecbaf1a4aa0d https://git.kernel.org/stable/c/2000016bab499074e6248ea85aeea7dd762355d9 https://git.kernel.org/stable/c/67b8bcbaed4777871bb0dcc888fb02a61 •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-26696 – nilfs2: fix hang in nilfs_lookup_dirty_data_buffers()
https://notcve.org/view.php?id=CVE-2024-26696
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix hang in nilfs_lookup_dirty_data_buffers() Syzbot reported a hang issue in migrate_pages_batch() called by mbind() and nilfs_lookup_dirty_data_buffers() called in the log writer of nilfs2. While migrate_pages_batch() locks a folio and waits for the writeback to complete, the log writer thread that should bring the writeback to completion picks up the folio being written back in nilfs_lookup_dirty_data_buffers() that it calls for subsequent log creation and was trying to lock the folio. Thus causing a deadlock. In the first place, it is unexpected that folios/pages in the middle of writeback will be updated and become dirty. Nilfs2 adds a checksum to verify the validity of the log being written and uses it for recovery at mount, so data changes during writeback are suppressed. Since this is broken, an unclean shutdown could potentially cause recovery to fail. Investigation revealed that the root cause is that the wait for writeback completion in nilfs_page_mkwrite() is conditional, and if the backing device does not require stable writes, data may be modified without waiting. Fix these issues by making nilfs_page_mkwrite() wait for writeback to finish regardless of the stable write requirement of the backing device. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: nilfs2: corrige un bloqueo en nilfs_lookup_dirty_data_buffers() Syzbot informó un problema de bloqueo en migrar_pages_batch() llamado por mbind() y nilfs_lookup_dirty_data_buffers() llamado en el escritor de registros de nilfs2. • https://git.kernel.org/stable/c/1d1d1a767206fbe5d4c69493b7e6d2a8d08cc0a0 https://git.kernel.org/stable/c/228742b2ddfb99dfd71e5a307e6088ab6836272e https://git.kernel.org/stable/c/862ee4422c38be5c249844a684b00d0dbe9d1e46 https://git.kernel.org/stable/c/98a4026b22ff440c7f47056481bcbbe442f607d6 https://git.kernel.org/stable/c/7e9b622bd0748cc104d66535b76d9b3535f9dc0f https://git.kernel.org/stable/c/8494ba2c9ea00a54d5b50e69b22c55a8958bce32 https://git.kernel.org/stable/c/ea5ddbc11613b55e5128c85f57b08f907abd9b28 https://git.kernel.org/stable/c/e38585401d464578d30f5868ff4ca5447 •
