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 •
CVSS: -EPSS: 0%CPEs: 9EXPL: 0CVE-2024-38552 – drm/amd/display: Fix potential index out of bounds in color transformation function
https://notcve.org/view.php?id=CVE-2024-38552
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix potential index out of bounds in color transformation function Fixes index out of bounds issue in the color transformation function. The issue could occur when the index 'i' exceeds the number of transfer function points (TRANSFER_FUNC_POINTS). The fix adds a check to ensure 'i' is within bounds before accessing the transfer function points. If 'i' is out of bounds, an error message is logged and the function returns false to indicate an error. Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:405 cm_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.red' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:406 cm_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.green' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:407 cm_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.blue' 1025 <= s32max En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amd/display: corrige un posible índice fuera de los límites en la función de transformación de color. • https://git.kernel.org/stable/c/b629596072e5fa901c84f9e88d845a696ee32942 https://git.kernel.org/stable/c/604c506ca43fce52bb882cff9c1fdf2ec3b4029c https://git.kernel.org/stable/c/e280ab978c81443103d7c61bdd1d8d708cf6ed6d https://git.kernel.org/stable/c/04bc4d1090c343025d69149ca669a27c5b9c34a7 https://git.kernel.org/stable/c/ced9c4e2289a786b8fa684d8893b7045ea53ef7e https://git.kernel.org/stable/c/98b8a6bfd30d07a19cfacdf82b50f84bf3360869 https://git.kernel.org/stable/c/4e8c8b37ee84b3b19c448d2b8e4c916d2f5b9c86 https://git.kernel.org/stable/c/123edbae64f4d21984359b99c6e79fcde •
