CVE-2026-43331

Summary of details (CVE-2026-43331): In the Linux kernel, a KCOV instrumentation issue in the x86/kexec path is resolved by disabling KCOV for the affected areas. The root cause is that load_segments() changes segment registers and invalidates the GS base KCOV relies on for per-CPU data, causing ...

CVE-2026-43289

CVE-2026-43289 relates to the Linux kernel kexec flow. The patch fixes kexec_load_purgatory() so image->start is derived from the purgatory_start symbol when present, rather than blindly locating e_entry within an SHF_EXECINSTR section. This prevents the entrypoint check from matching multiple...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the failure of KCOV detection after the x86 kexec operation, resulting in an invalid GS base...

PT-2026-38982

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description In the x86 architecture, the load segments function modifies segment registers, which invalidates the GS base used by KCOV for per-cpu data. When CONFIG KCOV is enabled, any subsequent...

CVE-2026-43240

A flaw was found in the Linux kernel's x86/kexec component. When a second-stage kernel is booted with a memory-limiting command, the Integrity Measurement Architecture IMA kexec buffer may be located outside the accessible memory range. This can lead to a kernel panic, effectively causing a Denia...

CVE-2026-43129

A flaw was found in the Linux kernel's Integrity Measurement Architecture IMA subsystem. When a second-stage kernel is booted via kexec with a memory-limiting command line, the IMA measurement buffer from the previous kernel may fall outside the new kernel's addressable memory. This out-of-bounds...
