OESA-2022-1517 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: A double free bug in packetsetring in net/packet/afpacket.c can be exploited by a local user through crafted syscalls to escalate privileges or deny service. We recommend upgrading kernel past the effected versions or rebuilding...

Vulnerability of the vmw_execbuf_copy_fence_user() function (drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c) in the vmwgfx module of Linux kernel, allowing an attacker to increase their privileges

The vulnerability of the vmwexecbufcopyfenceuser function drivers/gpu/drm/vmwgfx/vmwgfxexecbuf.c in the vmwgfx module of Linux operating systems is related to the use of memory after it is freed. Exploiting this vulnerability can allow an attacker to increase their privileges...

vmwgfx Driver File Descriptor Handling Priv Esc

If the vmwgfx driver fails to copy the 'fencerep' object to userland, it tries to recover by deallocating the already populated file descriptor. This is wrong, as the fd gets released via putunusedfd which shouldn't be used, as the fd table slot was already populated via the previous call to...

Design/Logic Flaw

In the Linux kernel 5.0.0-rc7 as distributed in ubuntu/linux.git on kernel.ubuntu.com, mounting a crafted f2fs filesystem image and performing some operations can lead to slab-out-of-bounds read access in ttmputpages in drivers/gpu/drm/ttm/ttmpagealloc.c. This is related to the vmwgfx or ttm modu...

CVE-2019-19927

CVE-2019-19927 affects Linux kernel 5.0.0-rc7 (as in ubuntu/linux.git) where mounting a crafted f2fs image and performing certain operations can cause slab-out-of-bounds read access in ttm_put_pages (ttm_page_alloc.c). The issue is linked to vmwgfx/ttm modules and may enable local, non-privileged...
