UBUNTU-CVE-2024-41006: Use After Free

Q: What level of access does an attacker need?

The vector is local and requires low privileges. No user interaction is required, and the attack complexity is rated low.

Q: What is the expected security impact?

The provided metrics indicate high availability impact. They do not indicate confidentiality or integrity impact for either the vulnerable component or subsequent components.

Q: Which Ubuntu kernel package families are identified?

The affected software list includes ubuntu/linux, ubuntu/linux-aws, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-oracle, ubuntu/linux-fips, ubuntu/linux-aws-fips, and ubuntu/linux-azure-fips.

Q: Can affected status be determined from a package version in this record?

No fixed or affected package version is provided in the available data. The record identifies the relevant Ubuntu kernel package families but does not include version-level remediation information.

Updated

In the Linux kernel, the following vulnerability has been resolved: netrom: Fix a memory leak in nrheartbeatexpiry() syzbot reported a memory leak in nrcreate() [0]. Commit 409db27e3a2e ("netrom: Fix use-after-free of a listening socket.") added sockhold() to the nrheartbeatexpiry() function, where a) a socket has a SOCKDESTROY flag or b) a listening socket has a SOCKDEAD flag. But in the case "a," when the SOCKDESTROY flag is set, the file descriptor has already been closed and the nrrelease() function has been called. So it makes no sense to hold the reference count because no one will call another nrdestroysocket() and put it as in the case "b." nrconnect nrestablishdatalink nrstartheartbeat nrrelease switch (nr->state) case NRSTATE3 nr->state = NRSTATE2 socksetflag(sk, SOCKDESTROY); nrrxframe nrprocessrxframe switch (nr->state) case NRSTATE2 nrstate2machine() nrdisconnect() nrsk(sk)->state = NRSTATE0 socksetflag(sk, SOCKDEAD) nrheartbeatexpiry switch (nr->state) case NRSTATE0 if (sockflag(sk, SOCKDESTROY) || (sk->skstate == TCPLISTEN && sockflag(sk, SOCKDEAD))) sockhold() // ( !!! ) nrdestroysocket() To fix the memory leak, let's call sockhold() only for a listening socket.
