keycloak: potential bypass of brute force protection

A vulnerability was found in Keycloak. This flaw allows attackers to bypass brute force protection by exploiting the timing of login attempts. By initiating multiple login requests simultaneously, attackers can exceed the configured limits for failed attempts before the system locks them out. Thi...

The vulnerability of the signal handler in the sshd(8) program of the FreeBSD operating system allows a hacker to execute arbitrary code in the root context.

The vulnerability of the signal handler in the sshd8 program of the FreeBSD operating system is related to the reutilization of previously freed memory due to concurrent access to resources. Exploiting this vulnerability allows a remote attacker to execute arbitrary code in the root context...

CVE-2024-43102

Concurrent removals of certain anonymous shared memory mappings by using the UMTXSHMDESTROY sub-request of UMTXOPSHM can lead to decreasing the reference count of the object representing the mapping too many times, causing it to be freed too early. A malicious code exercizing the UMTXSHMDESTROY...

Concurrent removals of certain anonymous shared memory mappings by using the UMTXSHMDESTROY sub-request of UMTXOPSHM can lead to decreasing the reference count of the object representing the mapping too many times, causing it to be freed too early. A malicious code exercizing the UMTXSHMDESTROY...

CVE-2024-43102

CVE-2024-43102 describes a kernel-level issue in FreeBSD involving concurrent removals of anonymous shared memory mappings via the UMTX_SHM_DESTROY sub-request of UMTX_OP_SHM. The root cause is that the reference count for the mapping object can be decremented too many times, causing premature fr...

CVE-2024-44991

CVE-2024-44991 affects the Linux kernel TCP stack: concurrent calls to tcp_sk_exit_batch() can race with inet_twsk_purge() across dying netns, risking timewait sockets of the exiting netns. The root cause: after the net/core/net_namespace change (commit that batches inet_twsk_purge), tcp_twsk_pur...

CVE-2024-44946

CVE-2024-44946 affects the Linux kernel kcm subsystem (kcm_sendmsg). The issue was a use-after-free/race: while MSG_MORE skb construction was in progress, another thread could touch it, leading to a double-free in kcm_release() when the skb remained in the write queue. The fix serialises kcm_send...
