CVE-2026-43407

The CVE-2026-43407 issue affects the Linux kernel libceph component, where a CEPH_MSG_AUTH_REPLY with a large payload_len could trigger an integer overflow and out-of-bounds read. The root cause is storing payload_len and related lengths in int, allowing negative values to underflow pointers. The...

CVE-2026-43386

The CVE-2026-43386 issue affects the Linux kernel rtl8723bs component, specifically in the rtw_restruct_wmm_ie path, where an insufficiently guarded access can cause an out-of-bounds read. The root cause is that the code accesses in_ie[i + 5] before ensuring i + 5 is within in_len, potentially le...

CVE-2026-43386 staging: rtl8723bs: fix potential out-of-bounds read in rtw_restruct_wmm_ie

In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: fix potential out-of-bounds read in rtwrestructwmmie The current code checks 'i + 5 inlen' at the end of the if statement. However, it accesses 'iniei + 5' before that check, which can lead to an out-of-bounds...

CVE-2026-43368

The CVE-2026-43368 entry concerns the Linux kernel DRM/i915 component (GEM shmem objects). A overflow can occur in the unsigned int .length field of a scatterlist when a scatterlists table for a GEM shmem object of 4 GB or more is built from folio-allocated pages, causing the total byte length of...
