CVE-2026-31715

A flaw was found in the Linux kernel's Flash-Friendly File System f2fs. A use-after-free vulnerability exists due to incorrect handling of page counts during concurrent write operations and unmounting. This can lead to a NULL pointer dereference, causing the system to panic and resulting in a...

CVE-2026-43043

A flaw was found in the Linux kernel's af-alg subsystem. When the AFALG interface chains a new afalgtsgl structure, it fails to unmark the end of a Scatter/Gather List SGL. This can lead to a NULL pointer dereference during a subsequent sendmsg operation, causing a kernel panic and resulting in a...

CVE-2026-35233

An unprivileged attacker can craft a user-space process with a malicious ELF binary containing an out-of-range shlink field. When root-level dtrace attaches to -- or instruments -- that process via dtrace -p , pid probes, or USDT, the ELF parser reads heap memory beyond the allocated section cach...

NULL Pointer Dereference

Overview Affected versions of this package are vulnerable to NULL Pointer Dereference in the TShape process. An attacker can cause the application to crash or become unresponsive by submitting a specially crafted VRML file that triggers dereference of a corrupt or unvalidated pointer during shape...

CVE-2026-43028

A flaw was found in the Linux kernel's netfilter xtables component. This vulnerability arises from the system's failure to ensure that certain names are properly ended with a null character before being used by functions designed for standard text strings. This oversight could lead to incorrect...

CVE-2026-37525

AGL app-framework-binder afb-daemon through v19.90.0 contains a privilege escalation vulnerability in the supervision Do command. The onsupervisioncall function in src/afb-supervision.c explicitly nullifies the request credentials by calling afbcontextchangecred&xreq-context, NULL before...

CVE-2026-43013

A flaw was found in the Linux kernel's net/mlx5 driver. An error in the mlx5lagdevaddmdev function can lead to the creation of debugfs entries without a valid LAG Link Aggregation Group context. This exposes interfaces that rely on a valid pointer, potentially leading to a NULL pointer dereferenc...
