UBUNTU-CVE-2025-38247
In the Linux kernel, the following vulnerability has been resolved: userns and mntidmap leak in opentreeattr2 Once wantmountsetattr has returned a positive, it does require finishmountkattr to release -mntuserns. Failing domountsetattr does not change that. As the result, we can end up leaking...

CVE-2022-50232
CVE-2022-50232 affects the Linux kernel on arm64 with FEAT_EPAN: UXN was not set on swapper PTEs, causing idmap_kpti_install_ng_mappings to panic when accessing __idmap_kpti_flag. Upstream fix sets UXN on swapper page tables; originated from a boot-flow refactor (commit c3cee924bd85) and a simple...

kernel: nfsd: call cache_put if xdr_reserve_space returns NULL
A flaw was found in the Linux kernel's Network File System Daemon nfsd component. This vulnerability occurs when the system attempts to allocate buffer space but fails, yet a related lookup operation succeeds. This leads to a resource leak where a cache entry is acquired but not properly released...
