Last modified

CVE-2023-53782 is a vulnerability of currently unknown severity. 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 the DCCP header. Actually, they also look at the DCCP sequence number, which is stored beyond 8 bytes, so an explicit pskb_may_pull() is required.. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
