In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix hang/underflow when transitioning to ODM4:1 [Why] Under some circumstances, disabling an OPTC and attempting to reclaim its OPP(s) for a different OPTC could cause a hang/underflow due to OPPs not being properly disconnected from the disabled OPTC. [How] Ensure that all OPPs are unassigned from an OPTC when it gets disabled. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amd/display: corrigió bloqueo/desbordamiento insuficiente al realizar la transición a ODM4:1 [Por qué] En algunas circunstancias, deshabilitar un OPTC e intentar reclamar sus OPP para otro OPTC podría causar un bloqueo/desbordamiento insuficiente debido a que los OPP no se desconectan correctamente del OPTC deshabilitado. [Cómo] Asegúrese de que todos los OPP estén desasignados de un OPTC cuando se deshabilite. • https://git.kernel.org/stable/c/ae62f1dde66a6f0eee98defc4c7a346bd5acd239 https://git.kernel.org/stable/c/4b6b479b2da6badff099b2e3abf0248936eefbf5 https://git.kernel.org/stable/c/e7b2b108cdeab76a7e7324459e50b0c1214c0386 •

In the Linux kernel, the following vulnerability has been resolved: btrfs: zoned: fix lock ordering in btrfs_zone_activate() The btrfs CI reported a lockdep warning as follows by running generic generic/129.

This is because we take fs_info->zone_active_bgs_lock after a block_group's lock in btrfs_zone_activate() while doing the opposite in other places.

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: fix a potential double-free in fs_any_create_groups When kcalloc() for ft->g succeeds but kvzalloc() for in fails, fs_any_create_groups() will free ft->g. However, its caller fs_any_create_table() will free ft->g again through calling mlx5e_destroy_flow_table(), which will lead to a double-free. Fix this by setting ft->g to NULL in fs_any_create_groups(). En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/mlx5e: corrige una posible double free en fs_any_create_groups Cuando kcalloc() para ft->g tiene éxito pero kvzalloc() para in falla, fs_any_create_groups() liberará ft-> gramo. Sin embargo, su llamador fs_any_create_table() liberará ft->g nuevamente llamando a mlx5e_destroy_flow_table(), lo que conducirá a un double free.
