SUSE CVE-2024-46762
In the Linux kernel, the following vulnerability has been resolved: xen: privcmd: Fix possible access to a freed kirqfd instance Nothing prevents simultaneous ioctl calls to privcmdirqfdassign and privcmdirqfddeassign. If that happens, it is possible that a kirqfd created and added to the...
SUSE CVE-2024-46701
In the Linux kernel, the following vulnerability has been resolved: libfs: fix infinite directory reads for offset dir After we switch tmpfs dir operations from simplediroperations to simpleoffsetdiroperations, every rename happened will fill new dentry to dest dir's maple...
Linux af_unix DoS
The vulnerability of the unixreleasesock/unixstreamsendmsg function in the afunix component is related to concurrent access to resources race condition. Exploiting this vulnerability could allow a attacker to cause service failures...
SUSE CVE-2024-45024
In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: fix hugetlb vs. core-mm PT locking We recently made GUP's common page table walking code to also walk hugetlb VMAs without most hugetlb special-casing, preparing for the future of having less hugetlb-specific page tab...

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...
FreeBSD sshd Signal Handler RCE
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...
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...

In the Linux kernel, the following vulnerability has been resolved: tcp: prevent concurrent execution of tcpskexitbatch Its possible that two threads call tcpskexitbatch concurrently, once from the cleanupnet workqueue, once from a task that failed to clone a new netns. In the latter case, error...
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...
