Technical description

In the Linux kernel, the following vulnerability has been resolved: ext4: replace BUG_ON with proper error handling in ext4_read_inline_folio Replace BUG_ON() with proper error handling when inline data size exceeds PAGE_SIZE. This prevents kernel panic and allows the system to continue running while properly reporting the filesystem corruption. The error is logged via ext4_error_inode(), the buffer head is released to prevent memory leak, and -EFSCORRUPTED is returned to indicate filesystem corruption.

CVE-2026-825904.3 MED

——7A weakness has been identified in Open5GS up to 2.7.7. The affected element is the function smf_nudm_sdm_handle_get of the file src/smf/nudm-handler.c of the component SMF. Executing a manipulation of the argument preemptCap can lead to reachable assertion. The attack may be launched remotely. Upgrading to version 2.8.0 is sufficient to fix this issue. This patch is called 4554405f29bffd7562abedbee63484825bd90cd5. You should upgrade the affected component.2d CVE-2026-300477.5 HIG

——5OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions 3.4.0 through 3.4.12, a crafted HTJ2K-compressed EXR file causes an unconditional process abort in any application that calls exr_start_read() on untrusted input, resulting in denial of service. The crash is triggered by a QCD marker whose lower five bits are zero, which OpenEXR passes into the vendored OpenJPH library while constructing the codestream and evaluating its quantization delta parameters. OpenJPH uses an assertion rather than a recoverable error to validate those bits, so any invalid value calls abort() directly and cannot be intercepted by surrounding error handling, a problem compounded by OpenEXR wrapping only its internal HT header parser in error handling while leaving the later codestream read and construction calls unprotected. This issue has been resolved in version 3.4.13.4d CVE-2026-781864.3 MED

——10A flaw has been found in Open5GS up to 2.8.0. This affects an unknown function of the file src/hss/hss-cx-path.c of the component HSS. This manipulation of the argument User-Name causes reachable assertion. The attack is possible to be carried out remotely. The exploit has been published and may be used. Patch name: c9abe09421eb99bbf1cd7862a3d375e58a4eb9e4. It is recommended to apply a patch to fix this issue.8d CVE-2026-633888.4 HIG

——1Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has a heap out-of-bounds write in bufferevent_sock.c when bufferevent_socket_set_conn_address_ copies a kernel-supplied AF_UNIX peer address into bufferevent_private.conn_address. Release builds compiled with NDEBUG disable the EVUTIL_ASSERT length guard, and the evhttp accept path can pass a 110-byte sockaddr from accept() into the 28-byte field. An unauthenticated local peer able to connect to an AF_UNIX listener can overwrite the adjacent dns_request pointer and heap data, causing memory corruption with confidentiality, integrity, and availability impact. This issue is fixed in versions 2.1.13 and 2.2.2-alpha.11d
