CVE-2026-53428

Summary: The CVE describes an unbounded memory allocation in the mdex/native codepath when parsing a user-supplied highlight_lines range in Markdown code blocks, enabling a denial-of-service via memory exhaustion. The affected components are mdex (v0.11.0 before 0.12.3) and mdex_native (v0.1.0 be...

CVE-2026-53265

A flaw was found in the Linux kernel's device mapper DM cache policy. A race condition exists where two processes attempting to invalidate cache blocks concurrently can lead to memory corruption. This can result in a local denial of service, causing the system to crash, or potentially corrupting...

postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...

CVE-2026-53293

A flaw was found in the Linux kernel's AMDGPU graphics driver. Multiple issues exist within the AMDGPUINFOREADMMRREG function, including an incorrect order of operations between the reset semaphore and the memory management lock, and memory allocation while holding the reset semaphore. These issu...

CVE-2026-53278

A flaw was found in the Linux kernel's armmpam component. This vulnerability occurs when the destroycomponentcfg function is called from mpamdisable before the configuration array has been properly allocated. This can lead to a null pointer dereference, potentially causing a system crash and...

CVE-2026-53285

A flaw was found in the Linux kernel's drm/amd/display component. When the dcn32enablephantomplane function attempts to allocate memory using kvzalloc within a floating-point unit FPU enabled region where software interrupts softirqs are disabled, it can trigger an error. This can lead to a kerne...

ImageMagick: ImageMagick: Denial of Service via missing memory request check

A flaw was found in ImageMagick. A remote attacker could exploit a missing check for maximum memory requests in the AcquireAlignedMemory function, leading to an out-of-memory condition. This vulnerability could result in a Denial of Service DoS, making the affected system or application unavailab...

CVE-2026-53319

A flaw was found in the Linux kernel's block writeback throttling blk-wbt component. The wbtinitenabledefault function used a warning mechanism WARNONONCE for expected failure paths during memory allocation or if writeback throttling was already registered. This could lead to spurious warnings, b...

K000161955: HarfBuzz vulnerability CVE-2026-22693

Security Advisory Description HarfBuzz is a text shaping engine. Prior to version 12.3.0, a null pointer dereference vulnerability exists in the SubtableUnicodesCache::create function located in src/hb-ot-cmap-table.hh. The function fails to check if hbmalloc returns NULL before using placement n...

kernel: RDMA/vmw_pvrdma: Fix double free on pvrdma_alloc_ucontext() error path

A flaw was found in the Linux kernel, specifically within the RDMA Remote Direct Memory Access vmwpvrdma module. This vulnerability is a double free, which means the system attempts to release the same memory resource twice. This can occur in an error handling path within the pvrdmaallocucontext...

UBUNTU-CVE-2026-58050

libssh2 through 1.11.1 reads an attacker-controlled 32-bit attribute count from a publickey-subsystem response and uses it in the allocation numattrs sizeoflibssh2publickeyattribute without bounds checking, so on 32-bit platforms the multiplication overflows to an undersized buffer. A malicious S...

UBUNTU-CVE-2026-58051

libssh2 through 1.11.1 grows its publickey list with SSH2REALLOC but does not zero-initialize new entries before parsing populates them, so a parse failure reaching the cleanup path leaves libssh2publickeylistfree operating on an uninitialized entry. A malicious SSH server offering the publickey...
