EUVD-2026-38916

In the Linux kernel, the following vulnerability has been resolved: gfs2: prevent NULL pointer dereference during unmount When flushing out outstanding glock work during an unmount, gfs2logflush can be called when sdp-sdjdesc has already been deallocated and sdp-sdjdesc is NULL. Commit 35264909e9...

CVE-2026-53048

The CVE concerns the Linux kernel gfs2 subsystem. During unmount, gfs2_log_flush() could dereference sdp->sd_jdesc when it had already been deallocated, leading to a NULL pointer dereference. A prior commit (35264909e9d1) added a NULL check in gfs2_log_flush(), but the dereference in gfs2_log_...

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-2026-38909

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix listxattr handling when the buffer is full BUG If an OCFS2 inode has both inline and block-based xattrs, listxattr can return a size larger than the caller's buffer when the inline names consume that buffer exactly...

CVE-2026-53041

CVE-2026-53041 concerns OCFS2 in the Linux kernel. When an OCFS2 inode has both inline and block-based xattrs, listxattr() could report a size larger than the caller’s buffer if inline names consumed the buffer exactly, triggering a kernel bug/DoS. The root cause was a refactor that used size == ...
