https://notcve.org/view.php?id=CVE-2024-26975
In the Linux kernel, the following vulnerability has been resolved: powercap: intel_rapl: Fix a NULL pointer dereference A NULL pointer dereference is triggered when probing the MMIO RAPL driver on platforms with CPU ID not listed in intel_rapl_common CPU model list. This is because the intel_rapl_common module still probes on such platforms even if 'defaults_msr' is not set after commit 1488ac990ac8 ("powercap: intel_rapl: Allow probing without CPUID match"). Thus the MMIO RAPL rp->priv->defaults is NULL when registering to RAPL framework. Fix the problem by adding sanity check to ensure rp->priv->rapl_defaults is always valid. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: powercap: intel_rapl: corrige una desreferencia de puntero NULL Se activa una desreferencia de puntero NULL al probar el controlador MMIO RAPL en plataformas con ID de CPU que no figuran en la lista de modelos de CPU intel_rapl_common. Esto se debe a que el módulo intel_rapl_common aún sondea en dichas plataformas incluso si 'defaults_msr' no está configurado después de confirmar 1488ac990ac8 ("powercap: intel_rapl: Permitir sondeo sin coincidencia de CPUID"). Por lo tanto, MMIO RAPL rp->priv->defaults es NULL cuando se registra en el marco RAPL. • https://git.kernel.org/stable/c/1488ac990ac886b1209aa9f94c0c66022bcc8827 https://git.kernel.org/stable/c/0641908b906a133f1494c312a71f9fecbe2b6c78 https://git.kernel.org/stable/c/9b254feb249981b66ccdb1dae54e757789a15ba1 https://git.kernel.org/stable/c/2f73cf2ae5e0f4e629db5be3a4380ff7807148e6 https://git.kernel.org/stable/c/2d1f5006ff95770da502f8cee2a224a1ff83866e •
CVSS: 5.8EPSS: 0%CPEs: 9EXPL: 0CVE-2024-26974 – crypto: qat - resolve race condition during AER recovery
https://notcve.org/view.php?id=CVE-2024-26974
In the Linux kernel, the following vulnerability has been resolved: crypto: qat - resolve race condition during AER recovery During the PCI AER system's error recovery process, the kernel driver may encounter a race condition with freeing the reset_data structure's memory. If the device restart will take more than 10 seconds the function scheduling that restart will exit due to a timeout, and the reset_data structure will be freed. However, this data structure is used for completion notification after the restart is completed, which leads to a UAF bug. This results in a KFENCE bug notice. BUG: KFENCE: use-after-free read in adf_device_reset_worker+0x38/0xa0 [intel_qat] Use-after-free read at 0x00000000bc56fddf (in kfence-#142): adf_device_reset_worker+0x38/0xa0 [intel_qat] process_one_work+0x173/0x340 To resolve this race condition, the memory associated to the container of the work_struct is freed on the worker if the timeout expired, otherwise on the function that schedules the worker. The timeout detection can be done by checking if the caller is still waiting for completion or not by using completion_done() function. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: crypto: qat: resuelve la condición de ejecución durante la recuperación de AER Durante el proceso de recuperación de errores del sistema PCI AER, el controlador del kernel puede encontrar una condición de ejecución al liberar la memoria de la estructura reset_data. Si el reinicio del dispositivo demora más de 10 segundos, la función que programa el reinicio se cerrará debido a un tiempo de espera y se liberará la estructura reset_data. • https://git.kernel.org/stable/c/d8cba25d2c68992a6e7c1d329b690a9ebe01167d https://git.kernel.org/stable/c/daba62d9eeddcc5b1081be7d348ca836c83c59d7 https://git.kernel.org/stable/c/8e81cd58aee14a470891733181a47d123193ba81 https://git.kernel.org/stable/c/d03092550f526a79cf1ade7f0dfa74906f39eb71 https://git.kernel.org/stable/c/4ae5a97781ce7d6ecc9c7055396535815b64ca4f https://git.kernel.org/stable/c/226fc408c5fcd23cc4186f05ea3a09a7a9aef2f7 https://git.kernel.org/stable/c/8a5a7611ccc7b1fba8d933a9f22a2e76859d94dc https://git.kernel.org/stable/c/0c2cf5142bfb634c0ef0a1a69cdf37950 •

https://notcve.org/view.php?id=CVE-2024-26973
In the Linux kernel, the following vulnerability has been resolved: fat: fix uninitialized field in nostale filehandles When fat_encode_fh_nostale() encodes file handle without a parent it stores only first 10 bytes of the file handle. However the length of the file handle must be a multiple of 4 so the file handle is actually 12 bytes long and the last two bytes remain uninitialized. This is not great at we potentially leak uninitialized information with the handle to userspace. Properly initialize the full handle length. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: fat: corrige el campo no inicializado en los identificadores de archivos notale Cuando fat_encode_fh_nostale() codifica el identificador de archivo sin un padre, almacena solo los primeros 10 bytes del identificador de archivo. • https://git.kernel.org/stable/c/ea3983ace6b79c96e6ab3d3837e2eaf81ab881e2 https://git.kernel.org/stable/c/9840d1897e28f8733cc1e38f97e044f987dc0a63 https://git.kernel.org/stable/c/f52d7663a10a1266a2d3871a6dd8fd111edc549f https://git.kernel.org/stable/c/a276c595c3a629170b0f052a3724f755d7c6adc6 https://git.kernel.org/stable/c/b7fb63e807c6dadf7ecc1d43448c4f1711d7eeee https://git.kernel.org/stable/c/c8cc05de8e6b5612b6e9f92c385c1a064b0db375 https://git.kernel.org/stable/c/03a7e3f2ba3ca25f1da1d3898709a08db14c1abb https://git.kernel.org/stable/c/74f852654b8b7866f15323685f1e178d3 •
CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2024-26972 – ubifs: ubifs_symlink: Fix memleak of inode->i_link in error path
https://notcve.org/view.php?id=CVE-2024-26972
In the Linux kernel, the following vulnerability has been resolved: ubifs: ubifs_symlink: Fix memleak of inode->i_link in error path For error handling path in ubifs_symlink(), inode will be marked as bad first, then iput() is invoked. If inode->i_link is initialized by fscrypt_encrypt_symlink() in encryption scenario, inode->i_link won't be freed by callchain ubifs_free_inode -> fscrypt_free_inode in error handling path, because make_bad_inode() has changed 'inode->i_mode' as 'S_IFREG'. Following kmemleak is easy to be reproduced by injecting error in ubifs_jnl_update() when doing symlink in encryption scenario: unreferenced object 0xffff888103da3d98 (size 8): comm "ln", pid 1692, jiffies 4294914701 (age 12.045s) backtrace: kmemdup+0x32/0x70 __fscrypt_encrypt_symlink+0xed/0x1c0 ubifs_symlink+0x210/0x300 [ubifs] vfs_symlink+0x216/0x360 do_symlinkat+0x11a/0x190 do_syscall_64+0x3b/0xe0 There are two ways fixing it: 1. Remove make_bad_inode() in error handling path. We can do that because ubifs_evict_inode() will do same processes for good symlink inode and bad symlink inode, for inode->i_nlink checking is before is_bad_inode(). 2. Free inode->i_link before marking inode bad. Method 2 is picked, it has less influence, personally, I think. • https://git.kernel.org/stable/c/2c58d548f5706d085c4b009f6abb945220460632 https://git.kernel.org/stable/c/3faea7810e2b3e9a9a92ef42d7e5feaeb8ff7133 https://git.kernel.org/stable/c/62b5ae00c2b835639002ce898ccb5d82c51073ae https://git.kernel.org/stable/c/6379b44cdcd67f5f5d986b73953e99700591edfa •
