CVE-2022-1016

A flaw was found in the Linux kernel in net/netfilter/nftablescore.c:nftdochain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. Mitigation On...

CVE-2022-1015

A flaw was found in the Linux kernel in linux/net/netfilter/nftablesapi.c of the netfilter subsystem. This flaw allows a local user to cause an out-of-bounds write issue. Mitigation In order to trigger the issue, it requires the ability to create user/net namespaces. On non-containerized...

CVE-2022-0886

A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat. Mitigation The given exploit needs...

CVE-2022-25636

An out-of-bounds OOB memory access flaw was found in nftfwddupnetdevoffload in net/netfilter/nfdupnetdev.c in the netfilter subcomponent in the Linux kernel due to a heap out-of-bounds write problem. This flaw allows a local attacker with a user account on the system to gain access to out-of-boun...

kernel: fs_context: heap overflow in legacy parameter handling

A heap-based buffer overflow flaw was found in the way the legacyparseparam function in the Filesystem Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged in case of unprivileged user namespaces enabled, otherwise needs namespaced CAPSYSADMIN privile...

CVE-2022-24122

A use-after-free vulnerability was found in the Linux kernel’s allocucounts in the kernel/ucount.c function. This flaw allows a local attacker with unprivileged user namespaces to cause a privilege escalation problem. Mitigation To mitigate this problem, disable unprivileged user namespaces: sysc...
