CVSS: -EPSS: 0%CPEs: 10EXPL: 0CVE-2024-38554 – ax25: Fix reference count leak issue of net_device
https://notcve.org/view.php?id=CVE-2024-38554
In the Linux kernel, the following vulnerability has been resolved: ax25: Fix reference count leak issue of net_device There is a reference count leak issue of the object "net_device" in ax25_dev_device_down(). When the ax25 device is shutting down, the ax25_dev_device_down() drops the reference count of net_device one or zero times depending on if we goto unlock_put or not, which will cause memory leak. In order to solve the above issue, decrease the reference count of net_device after dev->ax25_ptr is set to null. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ax25: Solucionar el problema de fuga del recuento de referencias de net_device Hay un problema de fuga del recuento de referencias del objeto "net_device" en ax25_dev_device_down(). Cuando el dispositivo ax25 se está apagando, ax25_dev_device_down() elimina el recuento de referencia de net_device una o cero veces dependiendo de si vamos a unlock_put o no, lo que provocará una pérdida de memoria. Para resolver el problema anterior, reduzca el recuento de referencias de net_device después de que dev->ax25_ptr se establezca en nulo. • https://git.kernel.org/stable/c/d01ffb9eee4af165d83b08dd73ebdf9fe94a519b https://git.kernel.org/stable/c/ef0a2a0565727a48f2e36a2c461f8b1e3a61922d https://git.kernel.org/stable/c/e2b558fe507a1ed4c43db2b0057fc6e41f20a14c https://git.kernel.org/stable/c/418993bbaafb0cd48f904ba68eeda052d624c821 https://git.kernel.org/stable/c/5ea00fc60676c0eebfa8560ec461209d638bca9d https://git.kernel.org/stable/c/9af0fd5c4453a44c692be0cbb3724859b75d739b https://git.kernel.org/stable/c/3ec437f9bbae68e9b38115c4c91de995f73f6bad https://git.kernel.org/stable/c/965d940fb7414b310a22666503d2af694 •
CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-38553 – net: fec: remove .ndo_poll_controller to avoid deadlocks
https://notcve.org/view.php?id=CVE-2024-38553
In the Linux kernel, the following vulnerability has been resolved: net: fec: remove .ndo_poll_controller to avoid deadlocks There is a deadlock issue found in sungem driver, please refer to the commit ac0a230f719b ("eth: sungem: remove .ndo_poll_controller to avoid deadlocks"). The root cause of the issue is that netpoll is in atomic context and disable_irq() is called by .ndo_poll_controller interface of sungem driver, however, disable_irq() might sleep. After analyzing the implementation of fec_poll_controller(), the fec driver should have the same issue. Due to the fec driver uses NAPI for TX completions, the .ndo_poll_controller is unnecessary to be implemented in the fec driver, so fec_poll_controller() can be safely removed. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: fec: elimine .ndo_poll_controller para evitar interbloqueos. • https://git.kernel.org/stable/c/7f5c6addcdc039c1a7c435857e6284ecac5d97c8 https://git.kernel.org/stable/c/d38625f71950e79e254515c5fc585552dad4b33e https://git.kernel.org/stable/c/accdd6b912c4219b8e056d1f1ad2e85bc66ee243 https://git.kernel.org/stable/c/87bcbc9b7e0b43a69d44efa5f32f11e32d08fa6f https://git.kernel.org/stable/c/c2e0c58b25a0a0c37ec643255558c5af4450c9f5 •

https://notcve.org/view.php?id=CVE-2024-38549
In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Add 0 size check to mtk_drm_gem_obj Add a check to mtk_drm_gem_init if we attempt to allocate a GEM object of 0 bytes. Currently, no such check exists and the kernel will panic if a userspace application attempts to allocate a 0x0 GBM buffer. Tested by attempting to allocate a 0x0 GBM buffer on an MT8188 and verifying that we now return EINVAL. En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: drm/mediatek: Agregar verificación de tamaño 0 a mtk_drm_gem_obj Agregar una verificación a mtk_drm_gem_init si intentamos asignar un objeto GEM de 0 bytes. Actualmente, no existe tal verificación y el kernel entrará en pánico si una aplicación de espacio de usuario intenta asignar un búfer GBM 0x0. Probado intentando asignar un búfer GBM 0x0 en un MT8188 y verificando que ahora devolvemos EINVAL. • https://git.kernel.org/stable/c/119f5173628aa7a0c3cf9db83460d40709e8241d https://git.kernel.org/stable/c/79078880795478d551a05acc41f957700030d364 https://git.kernel.org/stable/c/be34a1b351ea7faeb15dde8c44fe89de3980ae67 https://git.kernel.org/stable/c/d17b75ee9c2e44d3a3682c4ea5ab713ea6073350 https://git.kernel.org/stable/c/0e3b6f9123726858cac299e1654e3d20424cabe4 https://git.kernel.org/stable/c/13562c2d48c9ee330de1077d00146742be368f05 https://git.kernel.org/stable/c/af26ea99019caee1500bf7e60c861136c0bf8594 https://git.kernel.org/stable/c/9489951e3ae505534c4013db4e76b1b5a •

In the Linux kernel, the following vulnerability has been resolved: media: atomisp: ssh_css: Fix a null-pointer dereference in load_video_binaries The allocation failure of mycs->yuv_scaler_binary in load_video_binaries() is followed with a dereference of mycs->yuv_scaler_binary after the following call chain: sh_css_pipe_load_binaries() |-> load_video_binaries(mycs->yuv_scaler_binary == NULL) | |-> sh_css_pipe_unload_binaries() |-> unload_video_binaries() In unload_video_binaries(), it calls to ia_css_binary_unload with argument &pipe->pipe_settings.video.yuv_scaler_binary[i], which refers to the same memory slot as mycs->yuv_scaler_binary. Thus, a null-pointer dereference is triggered. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: media: atomisp: ssh_css: corrige una desreferencia de puntero nulo en load_video_binaries La falla de asignación de mycs->yuv_scaler_binary en load_video_binaries() va seguida de una desreferencia de mycs->yuv_scaler_binary después de siguiente cadena de llamadas: sh_css_pipe_load_binaries() |-> load_video_binaries(mycs->yuv_scaler_binary == NULL) | |-> sh_css_pipe_unload_binaries() |-> unload_video_binaries() En unload_video_binaries(), llama a ia_css_binary_unload con el argumento &pipe->pipe_settings.video.yuv_scaler_binary[i], que se refiere a la misma ranura de memoria que mycs->yuv_scaler_binary.
