https://notcve.org/view.php?id=CVE-2024-39493
In the Linux kernel, the following vulnerability has been resolved: crypto: qat - Fix ADF_DEV_RESET_SYNC memory leak Using completion_done to determine whether the caller has gone away only works after a complete call. Furthermore it's still possible that the caller has not yet called wait_for_completion, resulting in another potential UAF. Fix this by making the caller use cancel_work_sync and then freeing the memory safely. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: crypto: qat: corrige la pérdida de memoria ADF_DEV_RESET_SYNC. El uso de complete_done para determinar si la persona que llama se ha ido solo funciona después de una llamada completa. Además, aún es posible que la persona que llama aún no haya llamado a wait_for_completion, lo que genera otra posible UAF. • 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/7d42e097607c4d246d99225bf2b195b6167a210c https://git.kernel.org/stable/c/0c2cf5142bfb634c0ef0a1a69cdf37950 •

In the Linux kernel, the following vulnerability has been resolved: mailbox: mtk-cmdq: Fix pm_runtime_get_sync() warning in mbox shutdown The return value of pm_runtime_get_sync() in cmdq_mbox_shutdown() will return 1 when pm runtime state is active, and we don't want to get the warning message in this case. So we change the return value < 0 for WARN_ON(). En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mailbox: mtk-cmdq: corrige la advertencia pm_runtime_get_sync() en el apagado de mbox. El valor de retorno de pm_runtime_get_sync() en cmdq_mbox_shutdown() devolverá 1 cuando el estado de tiempo de ejecución pm esté activo, y no queremos recibir el mensaje de advertencia en este caso.

https://notcve.org/view.php?id=CVE-2024-39491
In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: cs35l56: Fix lifetime of cs_dsp instance The cs_dsp instance is initialized in the driver probe() so it should be freed in the driver remove(). Also fix a missing call to cs_dsp_remove() in the error path of cs35l56_hda_common_probe(). The call to cs_dsp_remove() was being done in the component unbind callback cs35l56_hda_unbind(). This meant that if the driver was unbound and then re-bound it would be using an uninitialized cs_dsp instance. It is best to initialize the cs_dsp instance in probe() so that it can return an error if it fails. The component binding API doesn't have any error handling so there's no way to handle a failure if cs_dsp was initialized in the bind. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ALSA: hda: cs35l56: Corrección de duración de la instancia cs_dsp La instancia cs_dsp se inicializa en el controlador probe() por lo que debe liberarse en el controlador remove(). • https://git.kernel.org/stable/c/73cfbfa9caea8eda54b4c6e49a9555533660aa1e https://git.kernel.org/stable/c/9054c474f9c219e58a441e401c0e6e38fe713ff1 https://git.kernel.org/stable/c/60d5e087e5f334475b032ad7e6ad849fb998f303 https://git.kernel.org/stable/c/d344873c4cbde249b7152d36a273bcc45864001e •
CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-39490 – ipv6: sr: fix missing sk_buff release in seg6_input_core
https://notcve.org/view.php?id=CVE-2024-39490
In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix missing sk_buff release in seg6_input_core The seg6_input() function is responsible for adding the SRH into a packet, delegating the operation to the seg6_input_core(). This function uses the skb_cow_head() to ensure that there is sufficient headroom in the sk_buff for accommodating the link-layer header. In the event that the skb_cow_header() function fails, the seg6_input_core() catches the error but it does not release the sk_buff, which will result in a memory leak. This issue was introduced in commit af3b5158b89d ("ipv6: sr: fix BUG due to headroom too small after SRH push") and persists even after commit 7a3f5b0de364 ("netfilter: add netfilter hooks to SRv6 data plane"), where the entire seg6_input() code was refactored to deal with netfilter hooks. The proposed patch addresses the identified memory leak by requiring the seg6_input_core() function to release the sk_buff in the event that skb_cow_head() fails. En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: ipv6: sr: corrige la versión faltante de sk_buff en seg6_input_core La función seg6_input() es responsable de agregar el SRH a un paquete, delegando la operación al seg6_input_core(). Esta función utiliza skb_cow_head() para garantizar que haya suficiente espacio libre en sk_buff para acomodar el encabezado de la capa de enlace. En caso de que la función skb_cow_header() falle, seg6_input_core() detecta el error pero no libera sk_buff, lo que provocará una pérdida de memoria. • https://git.kernel.org/stable/c/af3b5158b89d3bab9be881113417558c71b71ca4 https://git.kernel.org/stable/c/e8688218e38111ace457509d8f0cad75f79c1a7a https://git.kernel.org/stable/c/8f1fc3b86eaea70be6abcae2e9aa7e7b99453864 https://git.kernel.org/stable/c/f4df8c7670a73752201cbde215254598efdf6ce8 https://git.kernel.org/stable/c/f5fec1588642e415a3d72e02140160661b303940 https://git.kernel.org/stable/c/5447f9708d9e4c17a647b16a9cb29e9e02820bd9 •
