A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to achieve local privilege escalation.The perf_group_detach function did not check the event's siblings' attach_state before calling add_event_to_groups, but remove_on_exec made it possible to call list_del_event on before detaching from their group, making it possible to use a dangling pointer causing a ...

In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled

A use-after-free vulnerability was found in __nfs42_ssc_open in fs/nfs/nfs4file.c in the Linux kernel. This flaw allows an attacker to conduct a remote denial of service.

An out-of-bounds memory access flaw was found in the Linux kernel's XFS file system in how a user restores an XFS image after failure . This flaw allows a local user to crash or potentially escalate their privileges on the system. do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading to a race condition

A denial of service issue was found in the Linux kernel;rsquo;s smb2_ioctl_query_info function in the fs/cifs/smb2ops.c Common Internet File System due to an incorrect return from the memdup_user function. This flaw allows a local, privileged attacker to crash the system. When the KVM updates the guest's page table entry, it will first use get_user_pages_fast to pin the page, and when it fails ...

An issue was discovered in fs/io_uring.c in the Linux kernel through 5.11.8. It allows attackers to cause a denial of service because exit may be waiting to park a SQPOLL thread, but concurrently that SQPOLL thread is waiting for a signal to start, aka CID-3ebba796fa25. A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading to a possible out-of-bounds memory write in the Linux k ...

A flaw was found in the Linux kernel's networking subsystem within the RPL protocol's handling. This issue results from the improper handling of user-supplied data, which can lead to an assertion failure. This flaw allows an unauthenticated, remote attacker to create a denial of service condition on the system. A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can ...
