In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix double free issue during amdgpu module unload Flexible endpoints use DIGs from available inflexible endpoints, so only the encoders of inflexible links need to be freed. Otherwise, a double free issue may occur when unloading the amdgpu module.

In the Linux kernel, the following vulnerability has been resolved: ksmbd: add refcnt to ksmbd_conn struct When sending an oplock break request, opinfo->conn is used, But freed ->conn can be used on multichannel. This patch add a reference count to the ksmbd_conn struct so that it can be freed when it is no longer used. • https://git.kernel.org/stable/c/18f06bacc197d4ac9b518ad1c69999bc3d83e7aa https://git.kernel.org/stable/c/9fd3cde4628bcd3549ab95061f2bab74d2ed4f3b https://git.kernel.org/stable/c/e9dac92f4482a382e8c0fe1bc243da5fc3526b0c https://git.kernel.org/stable/c/ee426bfb9d09b29987369b897fe9b6485ac2be27 •
CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-49987 – bpftool: Fix undefined behavior in qsort(NULL, 0, ...)
https://notcve.org/view.php?id=CVE-2024-49987
In the Linux kernel, the following vulnerability has been resolved: bpftool: Fix undefined behavior in qsort(NULL, 0, ...) When netfilter has no entry to display, qsort is called with qsort(NULL, 0, ...). This results in undefined behavior, as UBSan reports: net.c:827:2: runtime error: null pointer passed as argument 1, which is declared to never be null Although the C standard does not explicitly state whether calling qsort with a NULL pointer when the size is 0 constitutes undefined behavior, Section 7.1.4 of the C standard (Use of library functions) mentions: "Each of the following statements applies unless explicitly stated otherwise in the detailed descriptions that follow: If an argument to a function has an invalid value (such as a value outside the domain of the function, or a pointer outside the address space of the program, or a null pointer, or a pointer to non-modifiable storage when the corresponding parameter is not const-qualified) or a type (after promotion) not expected by a function with variable number of arguments, the behavior is undefined." To avoid this, add an early return when nf_link_info is NULL to prevent calling qsort with a NULL pointer. • https://git.kernel.org/stable/c/c2d9f9a7837ab29ccae0c42252f17d436bf0a501 https://git.kernel.org/stable/c/2e0f6f33f2aa87493b365a38a8fd87b8854b7734 https://git.kernel.org/stable/c/c208b02827eb642758cef65641995fd3f38c89af https://git.kernel.org/stable/c/f04e2ad394e2755d0bb2d858ecb5598718bf00d5 •
CVSS: -EPSS: 0%CPEs: 11EXPL: 0CVE-2024-49982 – aoe: fix the potential use-after-free problem in more places
https://notcve.org/view.php?id=CVE-2024-49982
In the Linux kernel, the following vulnerability has been resolved: aoe: fix the potential use-after-free problem in more places For fixing CVE-2023-6270, f98364e92662 ("aoe: fix the potential use-after-free problem in aoecmd_cfg_pkts") makes tx() calling dev_put() instead of doing in aoecmd_cfg_pkts(). It avoids that the tx() runs into use-after-free. Then Nicolai Stange found more places in aoe have potential use-after-free problem with tx(). e.g. revalidate(), aoecmd_ata_rw(), resend(), probe() and aoecmd_cfg_rsp(). Those functions also use aoenet_xmit() to push packet to tx queue. So they should also use dev_hold() to increase the refcnt of skb->dev. On the other hand, moving dev_put() to tx() causes that the refcnt of skb->dev be reduced to a negative value, because corresponding dev_hold() are not called in revalidate(), aoecmd_ata_rw(), resend(), probe(), and aoecmd_cfg_rsp(). This patch fixed this issue. • https://git.kernel.org/stable/c/ad80c34944d7175fa1f5c7a55066020002921a99 https://git.kernel.org/stable/c/1a54aa506b3b2f31496731039e49778f54eee881 https://git.kernel.org/stable/c/faf0b4c5e00bb680e8e43ac936df24d3f48c8e65 https://git.kernel.org/stable/c/7dd09fa80b0765ce68bfae92f4e2f395ccf0fba4 https://git.kernel.org/stable/c/74ca3ef68d2f449bc848c0a814cefc487bf755fa https://git.kernel.org/stable/c/eb48680b0255a9e8a9bdc93d6a55b11c31262e62 https://git.kernel.org/stable/c/f98364e926626c678fb4b9004b75cacf92ff0662 https://git.kernel.org/stable/c/079cba4f4e307c69878226fdf5228c20a •
