In the Linux kernel, the following vulnerability has been resolved: packet: use consistent hardheaderlen in non-ring send paths packetsnd reads dev-hardheaderlen multiple times while allocating and constructing an skb. Device reconfiguration can change this value concurrently, for example through...

UBUNTU-CVE-2026-74518

In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: fix list corruption in allocatefileregionentries allocatefileregionentries tops up resv-regioncache with freshly allocated fileregion descriptors. The allocation uses GFPKERNEL, so resv-lock is dropped around it: the...

CVE-2026-73631

Apache Struts version 7.2.1 is vulnerable to a session data exposure issue within its JSON plugin . The root cause is that per-request parsing state is not properly isolated and can be shared across concurrent requests in a multithreaded context. This allows data from one request to become observ...
