CVE-2026-45959

A flaw was found in the Linux kernel's crypto: ccp module. An incorrect cleanup usage of the kfree function, which is used for memory deallocation, with a local pointer variable could lead to an invalid deallocation of a stack address. This issue can result in a system crash, causing a Denial of...

CVE-2026-45986

A flaw was found in the Linux kernel's cryptographic module, specifically within the ccmacdigest function of the ccree component. This vulnerability is a memory leak that occurs when a specific mapping operation fails to release allocated memory. Over time, this unreleased memory could lead to a...

CVE-2026-45994

A flaw was found in the Linux kernel's ibmasm module. This vulnerability, an out-of-bounds read in the commandfilewrite function, allows an attacker to cause the system to read beyond the intended memory boundaries. By manipulating the allocation size and header fields, an attacker can trigger th...

httpd: mod_proxy_ajp: off-by-one out-of-bounds reads in AJP getter functions

A flaw was found in the modproxyajp module of httpd. When processing AJP Apache JServ Protocol messages, the AJP getter functions attempt to read data beyond the allocated buffer size, allowing an attacker or a malformed request to cause an out-of-bounds read. This issue leads to a denial of...

httpd: mod_proxy_ajp: heap-based buffer over-read and memory disclosure in ajp_parse_data()

A flaw was found in the modproxyajp module of httpd. When processing AJP Apache JServ Protocol messages, the ajpparsedata function attempts to read data beyond the allocated buffer size, allowing an attacker or a malformed request to cause a heap-based buffer over-read. This issue potentially lea...

httpd: mod_authn_socache: NULL pointer dereference can cause a child process crash

A flaw was found in the modauthnsocache module of httpd. This vulnerability allows an unauthenticated remote user to crash a child process due to a NULL pointer dereference when the server is operating in a caching forward proxy configuration...

httpd: mod_proxy_ajp: heap-based buffer over-read due to missing null-termination check

A flaw was found in the modproxyajp module of httpd. When processing AJP Apache JServ Protocol messages, the server fails to properly check if a string is null-terminated before attempting to read it, allowing an attacker or a malformed request to cause a heap-based buffer over-read. This issue...

httpd: mod_proxy_ajp: off-by-one out-of-bounds reads in AJP getter functions

A flaw was found in the modproxyajp module of httpd. When processing AJP Apache JServ Protocol messages, the AJP getter functions attempt to read data beyond the allocated buffer size, allowing an attacker or a malformed request to cause an out-of-bounds read. This issue leads to a denial of...

CVE-2026-46022

A flaw was found in the Linux kernel's ibmasm module. A compromised service processor can exploit this by manipulating specific hardware registers, causing the system to read data from an unintended memory location. This out-of-bounds read can lead to a system crash, resulting in a Denial of...

CVE-2026-8359

When processing a request with a URL path starting with /status or /sysinfo, WOSHttpStatusModule.dll is to be loaded to handle such URL patterns. The WOSBinLoadHttpModule function in the dll would be called to set up a "module" object for that module. However, WOSHttpStatusModule.dll is not prese...

CVE-2026-24199

NVIDIA Display Driver for Linux contains a vulnerability in a kernel module, where a user could cause a race condition by reordering compiler or processor memory instructions. A successful exploit of this vulnerability might lead to denial of service...

CVE-2026-46034

A flaw was found in the Linux kernel's vfio/cdx module. A local user can cause a system crash by improperly configuring Message Signaled Interrupts MSI before they are set up. This can lead to a NULL pointer dereference, resulting in a Denial of Service DoS for the system...

CVE-2026-47270 pam_usb: strtok() race condition in multi-threaded PAM hosts can corrupt deny_remote result

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, pamusb is a PAM module loaded into the host process sudo, login, GDM, GNOME Shell.
