A denial-of-service issue was discovered in MediaWiki before 1.35.6, 1.36.x before 1.36.4, and 1.37.x before 1.37.2. When many files exist, requesting Special:NewFiles with actor as a condition can result in a very long running query.

There exists a use-after-free in io_uring in the Linux kernel. Signalfd_poll() and binder_poll() use a waitqueue whose lifetime is the current task. It will send a POLLFREE notification to all waiters before the queue is freed. Unfortunately, the io_uring poll doesn't handle POLLFREE. This allows a use-after-free to occur if a signalfd or binder fd is polled with io_uring poll, and the waitqueue gets freed. We recommend upgrading past commit fc78b2fc21f10c4c9c4d5d659a685710ffa63659

Those using Jettison to parse untrusted XML or JSON data may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stackoverflow. This effect may support a denial of service attack.

An out-of-bounds(OOB) memory access vulnerability was found in vmwgfx driver in drivers/gpu/vmxgfx/vmxgfx_kms.c in GPU component in the Linux kernel with device file '/dev/dri/renderD128 (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing a denial of service(DoS).

A vulnerability was found in the PCS project. This issue occurs due to incorrect permissions on a Unix socket used for internal communication between PCS daemons. A privilege escalation could happen by obtaining an authentication token for a hacluster user. With the "hacluster" token, this flaw allows an attacker to have complete control over the cluster managed by PCS.

The tinygltf library uses the C library function wordexp() to perform file path expansion on untrusted paths that are provided from the input file. This function allows for command injection by using backticks. An attacker could craft an untrusted path input that would result in a path expansion. We recommend upgrading to 2.6.0 or past commit 52ff00a38447f06a17eab1caa2cf0730a119c751

An issue was discovered in the Linux kernel before 5.19. In pxa3xx_gcu_write in drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict of size_t versus int, causing an integer overflow and bypassing the size check. After that, because it is used as the third argument to copy_from_user(), a heap overflow may occur. NOTE: the original discoverer disputes that the overflow can actually happen.
