The vulnerability is a win32k window object type confusion leading to an OOB (out-of-bounds) write which can be used to create arbitrary memory read and write capabilities within the Windows kernel to achieve elevated privileges.
A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c.
A heap-based buffer overflow flaw was found in the way the legacy_parse_param 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 CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system.
The bpf verifier(kernel/bpf/verifier.c) did not properly restrict several *_OR_NULL pointer types which allows these types to do pointer arithmetic. An unprivileged user could use this flaw to escalate their privileges on a system. Setting parameter "kernel.unprivileged_bpf_disabled=1" prevents such privilege escalation by restricting access to bpf(2) call.
An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
net/netfilter/nf_dup_netdev.c in the Linux kernel 5.4 through 5.6.10 allows local users to gain privileges because of a heap out-of-bounds write. This is related to nf_tables_offload.
An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
An out-of-bounds (OOB) memory write flaw was found in the Linux kernel's watch_queue event notification subsystem. This flaw can overwrite parts of the kernel state, potentially allowing a local user to gain privileged access or cause a denial of service on the system.
The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands
An elevation of privilege vulnerability exists when the Windows Print Spooler service improperly allows arbitrary writing to the file system.
