In the Linux kernel, the following vulnerability has been resolved: dccp: Fix out of bounds access in DCCP error handler There was a previous attempt to fix an out-of-bounds access in the DCCP error handlers, but that fix assumed that the error handlers only want to access the first 8 bytes of th...

CVE-2023-53839

The CVE-2023-53839 entry concerns a data race in the Linux kernel's DCCP path. Specifically, dccp_sendmsg() and do_dccp_getsockopt() read dp->dccps_mss_cache before acquiring the socket lock, allowing a race with concurrent updates. The fix adds READ_ONCE()/WRITE_ONCE() annotations and modifie...

CVE-2023-53782

The CVE-2023-53782 entry is actionable and supported by connected advisories: in the Linux kernel, the DCCP error handler fix addresses an out-of-bounds access by ensuring proper checks with pskb_may_pull(), since the error handler may inspect the DCCP sequence number beyond the first 8 bytes. Th...
