CVE-2026-53047

A flaw was found in the Linux kernel's EFI Extensible Firmware Interface capsule loader. An incorrect size calculation during memory reallocation for physical addresses can lead to an undersized buffer. This issue, specifically on 32-bit systems with Physical Address Extension PAE, may result in ...

Linux Distros Unpatched Vulnerability : CVE-2026-53047

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - efi/capsule-loader: fix incorrect sizeof in phys array reallocation The krealloc call for capinfo-phys in eficapsulesetupinfo uses sizeofphysaddrt instead of...

EUVD-2026-38915

In the Linux kernel, the following vulnerability has been resolved: efi/capsule-loader: fix incorrect sizeof in phys array reallocation The krealloc call for capinfo-phys in eficapsulesetupinfo uses sizeofphysaddrt instead of sizeofphysaddrt, which might be causing an undersized allocation. The...

CVE-2026-53047

CVE-2026-53047 affects the Linux kernel’s efi/capsule-loader. The vulnerability arises from a mis-sized allocation in __efi_capsule_setup_info(): the krealloc() for cap_info->phys uses sizeof(phys_addr_t *) instead of sizeof(phys_addr_t). This can produce an undersized allocation, inconsistent...

EUVD-2026-38641

Improper Validation of Specified Index, Position, or Offset in Input vulnerability in Google go-attestation. parseEfiSignatureList does not advance the buffer past vendor bytes before reading entries. For hashSHA256SigGUID lists, this allows attacker-controlled vendor header bytes to be appended ...
