https://notcve.org/view.php?id=CVE-2024-50186
In the Linux kernel, the following vulnerability has been resolved: net: explicitly clear the sk pointer, when pf->create fails We have recently noticed the exact same KASAN splat as in commit 6cd4a78d962b ("net: do not leave a dangling sk pointer, when socket creation fails"). The problem is that commit did not fully address the problem, as some pf->create implementations do not use sk_common_release in their error paths. For example, we can use the same reproducer as in the above commit, but changing ping to arping. arping uses AF_PACKET socket and if packet_create fails, it will just sk_free the allocated sk object. While we could chase all the pf->create implementations and make sure they NULL the freed sk object on error from the socket, we can't guarantee future protocols will not make the same mistake. So it is easier to just explicitly NULL the sk pointer upon return from pf->create in __sock_create. We do know that pf->create always releases the allocated sk object on error, so if the pointer is not NULL, it is definitely dangling. • https://git.kernel.org/stable/c/78e4aa528a7b1204219d808310524344f627d069 https://git.kernel.org/stable/c/893eeba94c40d513cd0fe6539330ebdaea208c0e https://git.kernel.org/stable/c/454c454ed645fed051216b79622f7cb69c1638f5 https://git.kernel.org/stable/c/6cd4a78d962bebbaf8beb7d2ead3f34120e3f7b2 https://git.kernel.org/stable/c/5dfe2408fd7dc4d2e7ac38a116ff0a37b1cfd3b9 https://git.kernel.org/stable/c/daf462ff3cde6ecf22b98d9ae770232c10d28de2 https://git.kernel.org/stable/c/b7d22a79ff4e962b8af5ffe623abd1d6c179eb9f https://git.kernel.org/stable/c/563e6892e21d6ecabdf62103fc4e7b326 •

In the Linux kernel, the following vulnerability has been resolved: mptcp: handle consistently DSS corruption Bugged peer implementation can send corrupted DSS options, consistently hitting a few warning in the data path. Use DEBUG_NET assertions, to avoid the splat on some builds and handle consistently the error, dumping related MIBs and performing fallback and/or reset according to the subflow type. • https://git.kernel.org/stable/c/6771bfd9ee2460c13e38c0cd46a3afb5404ae716 https://git.kernel.org/stable/c/fde99e972b8f88cebe619241d7aa43d288ef666a https://git.kernel.org/stable/c/12c1676d598e3b8dd92a033b623b792cc2ea1ec5 https://git.kernel.org/stable/c/35668f8ec84f6c944676e48ecc6bbc5fc8e6fe25 https://git.kernel.org/stable/c/b8be15d1ae7ea4eedd547c3b3141f592fbddcd30 https://git.kernel.org/stable/c/8bfd391bde685df7289b928ce8876a3583be4bfb https://git.kernel.org/stable/c/e32d262c89e2b22cb0640223f953b548617ed8a6 •

In the Linux kernel, the following vulnerability has been resolved: virtio_pmem: Check device status before requesting flush If a pmem device is in a bad status, the driver side could wait for host ack forever in virtio_pmem_flush(), causing the system to hang. So add a status check in the beginning of virtio_pmem_flush() to return early if the device is not activated. • https://git.kernel.org/stable/c/59ac565c6277d4be6661e81ea6a7f3ca2c5e4e36 https://git.kernel.org/stable/c/4ce662fe4be6fbc2595d9ef4888b2b6e778c99ed https://git.kernel.org/stable/c/9a2bc9b6f929a2ce1ebe4d1a796ddab37568c5b4 https://git.kernel.org/stable/c/6a5ca0ab94e13a1474bf7ad8437a975c2193618f https://git.kernel.org/stable/c/b01793cc63dd39c8f12b9a3d8dc115fbebb19e2a https://git.kernel.org/stable/c/ce7a3a62cc533c922072f328fd2ea2fd7cb893d4 https://git.kernel.org/stable/c/e25fbcd97cf52c3c9824d44b5c56c19673c3dd50 •

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Ensure DA_ID handling completion before deleting an NPIV instance Deleting an NPIV instance requires all fabric ndlps to be released before an NPIV's resources can be torn down. Failure to release fabric ndlps beforehand opens kref imbalance race conditions. Fix by forcing the DA_ID to complete synchronously with usage of wait_queue. • https://git.kernel.org/stable/c/0857b1c573c0b095aa778bb26d8b3378172471b6 https://git.kernel.org/stable/c/0ef6e016eb53fad6dc44c3253945efb43a3486b9 https://git.kernel.org/stable/c/bbc525409bfe8e5bff12f5d18d550ab3e52cdbef https://git.kernel.org/stable/c/0a3c84f71680684c1d41abb92db05f95c09111e8 •

https://notcve.org/view.php?id=CVE-2024-50182
In the Linux kernel, the following vulnerability has been resolved: secretmem: disable memfd_secret() if arch cannot set direct map Return -ENOSYS from memfd_secret() syscall if !can_set_direct_map(). This is the case for example on some arm64 configurations, where marking 4k PTEs in the direct map not present can only be done if the direct map is set up at 4k granularity in the first place (as ARM's break-before-make semantics do not easily allow breaking apart large/gigantic pages). More precisely, on arm64 systems with !can_set_direct_map(), set_direct_map_invalid_noflush() is a no-op, however it returns success (0) instead of an error. This means that memfd_secret will seemingly "work" (e.g. • https://git.kernel.org/stable/c/1507f51255c9ff07d75909a84e7c0d7f3c4b2f49 https://git.kernel.org/stable/c/d0ae6ffa1aeb297aef89f49cfb894a83c329ebad https://git.kernel.org/stable/c/5ea0b7af38754d2b45ead9257bca47e84662e926 https://git.kernel.org/stable/c/7caf966390e6e4ebf42775df54e7ee1f280ce677 https://git.kernel.org/stable/c/757786abe4547eb3d9d0e8350a63bdb0f9824af2 https://git.kernel.org/stable/c/532b53cebe58f34ce1c0f34d866f5c0e335c53c6 •
