In the Linux kernel, the following vulnerability has been resolved: userfaultfd: prevent registration of special VMAs Vova Tokarev says: userfaultfd allows registration on shadow stack VMAs. With userfaultfd access, you can register on the shadow stack, discard a page ... and inject a page with...

CVE-2026-68164

The CVE concerns the Linux kernel DAMON subsystem, specifically the function damon_set_regions() in mm/damon/core. The root cause was that input ranges were assumed to be sorted and non-overlapping, but a prior commit removed validation, allowing overlapping ranges. The consequence can be odd mon...

CVE-2026-68164 mm/damon/core: disallow overlapping input ranges for damon_set_regions()

In the Linux kernel, the following vulnerability has been resolved: mm/damon/core: disallow overlapping input ranges for damonsetregions damonsetregions assumes the input ranges are sorted by the address and don't overlap each other. Hence the assumption was initially to be explicitly validated...

In the Linux kernel, the following vulnerability has been resolved: libceph: bound pgtemp,upmap,upmapitems length to CEPHPGMAXSIZE decodepgtemp decodes an user-controlled length but only rejects values large enough to overflow the allocation; it does not bound it to CEPHPGMAXSIZE. The helper back...

CVE-2026-68159

CVE-2026-68159 (Linux kernel libceph bound check) : The issue occurs when decoding pg_temp/pg_upmap entries in libceph within the kernel. __decode_pg_temp() may accept a user-controlled length that overflows the allocation, and the same applies to __decode_pg_upmap_items(); decoded data is later ...

CVE-2026-68156

The CVE-2026-68156 issue affects the Linux kernel libceph path: during an authorizer update, ceph_x_update_authorizer() may rebuild the authorizer and, if the new authorizer won’t fit in the existing buffer, it frees the old buffer while auth->authorizer_buf still points to the freed memory. A...

CVE-2026-68154

The CVE-2026-68154 vulnerability affects the Linux kernel’s libceph component, where CRUSH map decoding accepts bucket type 0 (reserved for devices) can let a malformed map cause a negative bucket ID to index the OSD weight array, leading to denial of service. The issue is fixed by rejecting zero...
