SUSE-SU-2022:3463-1 Security update for the Linux Kernel (Live Patch 27 for SLE 15 SP2)

This update for the Linux Kernel 5.3.18-15020024115 fixes several issues. The following security issues were fixed: - CVE-2022-39188: Fixed a race condition between unmapmappingrange and munmap on VMPFNMAP mappings leads to stale TLB entry bsc1203116. - CVE-2022-29581: Fixed an improper Update of...

An internal reference count is held on the buffer pool incremented every time a new buffer is created from the pool. The reference count is maintained as an int; on LP64 systems this can cause the reference count to overflow if the client creates a large number of wl_shm buffer objects or if it can coerce the server to create a large number of external references to the buffer storage. With the reference count overflowing a use-after-free can be constructed on the wl_shm_pool tracking structure where values may be incremented or decremented; it may also be possible to construct a limited oracle to leak 4 bytes of server-side memory to the attacking client at a time.

CVE-2021-3782

Wayland vulnerable component: wl_shm and wl_shm_pool in the Wayland buffer handling. CVE-2021-3782 is a reference-count overflow on LP64 systems when objects are created from the buffer pool, which can lead to a use-after-free in the wl_shm_pool tracking structure and, in some cases, a limited or...
