https://notcve.org/view.php?id=CVE-2024-36960
In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Fix invalid reads in fence signaled events Correctly set the length of the drm_event to the size of the structure that's actually used. The length of the drm_event was set to the parent structure instead of to the drm_vmw_event_fence which is supposed to be read. drm_read uses the length parameter to copy the event to the user space thus resuling in oob reads. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/vmwgfx: corrige lecturas no válidas en eventos señalizados de valla establezca correctamente la longitud de drm_event al tamaño de la estructura que realmente se utiliza. La longitud de drm_event se configuró en la estructura principal en lugar de en drm_vmw_event_fence que se supone debe leerse. drm_read usa el parámetro de longitud para copiar el evento al espacio del usuario, lo que resulta en lecturas oob. This vulnerability allows local attackers to disclose sensitive information on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of vmw fence events. • https://git.kernel.org/stable/c/8b7de6aa84682a3396544fd88cd457f95484573a https://git.kernel.org/stable/c/2f527e3efd37c7c5e85e8aa86308856b619fa59f https://git.kernel.org/stable/c/cef0962f2d3e5fd0660c8efb72321083a1b531a9 https://git.kernel.org/stable/c/3cd682357c6167f636aec8ac0efaa8ba61144d36 https://git.kernel.org/stable/c/b7bab33c4623c66e3398d5253870d4e88c52dfc0 https://git.kernel.org/stable/c/0dbfc73670b357456196130551e586345ca48e1b https://git.kernel.org/stable/c/7b5fd3af4a250dd0a2a558e07b43478748eb5d22 https://git.kernel.org/stable/c/deab66596dfad14f1c54eeefdb7242834 • CWE-125: Out-of-bounds Read •

In the Linux kernel, the following vulnerability has been resolved: pinctrl: devicetree: fix refcount leak in pinctrl_dt_to_map() If we fail to allocate propname buffer, we need to drop the reference count we just took. Because the pinctrl_dt_free_maps() includes the droping operation, here we call it directly. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: pinctrl: devicetree: corrige la fuga de recuento de referencia en pinctrl_dt_to_map() Si no asignamos el búfer de nombre de propiedad, debemos eliminar el recuento de referencias que acabamos de tomar. Debido a que pinctrl_dt_free_maps() incluye la operación de eliminación, aquí la llamamos directamente. • https://git.kernel.org/stable/c/a988dcd3dd9e691c5ccc3324b209688f3b5453e9 https://git.kernel.org/stable/c/040f726fecd88121f3b95e70369785ad452dddf9 https://git.kernel.org/stable/c/777430aa4ddccaa5accec6db90ffc1d47f00d471 https://git.kernel.org/stable/c/97e5b508e96176f1a73888ed89df396d7041bfcb https://git.kernel.org/stable/c/91d5c5060ee24fe8da88cd585bb43b843d2f0dce https://git.kernel.org/stable/c/aaf552c5d53abe4659176e099575fe870d2e4768 https://git.kernel.org/stable/c/b4d9f55cd38435358bc16d580612bc0d798d7b4c https://git.kernel.org/stable/c/5834a3a98cd266ad35a229923c0adbd0a •

In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: avoid off-by-one read from userspace We try to access count + 1 byte from userspace with memdup_user(buffer, count + 1). However, the userspace only provides buffer of count bytes and only these count bytes are verified to be okay to access. To ensure the copied buffer is NUL terminated, we use memdup_user_nul instead.

In the Linux kernel, the following vulnerability has been resolved: thermal/debugfs: Free all thermal zone debug memory on zone removal Because thermal_debug_tz_remove() does not free all memory allocated for thermal zone diagnostics, some of that memory becomes unreachable after freeing the thermal zone's struct thermal_debugfs object. Address this by making thermal_debug_tz_remove() free all of the memory in question. Cc :6.8+ <stable@vger.kernel.org> # 6.8+ En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Thermal/debugfs: libera toda la memoria de depuración de la zona térmica al eliminar la zona.
