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 •

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 •

In the Linux kernel, the following vulnerability has been resolved: i2c: stm32f7: Do not prepare/unprepare clock during runtime suspend/resume In case there is any sort of clock controller attached to this I2C bus controller, for example Versaclock or even an AIC32x4 I2C codec, then an I2C transfer triggered from the clock controller clk_ops .prepare callback may trigger a deadlock on drivers/clk/clk.c prepare_lock mutex. This is because the clock controller first grabs the prepare_lock mutex and then performs the prepare operation, including its I2C access. The I2C access resumes this I2C bus controller via .runtime_resume callback, which calls clk_prepare_enable(), which attempts to grab the prepare_lock mutex again and deadlocks. Since the clock are already prepared since probe() and unprepared in remove(), use simple clk_enable()/clk_disable() calls to enable and disable the clock on runtime suspend and resume, to avoid hitting the prepare_lock mutex. • https://git.kernel.org/stable/c/4e7bca6fc07bf9526d797b9787dcb21e40cd10cf https://git.kernel.org/stable/c/d6f1250a4d5773f447740b9fe37b8692105796d4 https://git.kernel.org/stable/c/9b8bc33ad64192f54142396470cc34ce539a8940 https://git.kernel.org/stable/c/1883cad2cc629ded4a3556c0bbb8b42533ad8764 https://git.kernel.org/stable/c/c2024b1a583ab9176c797ea1e5f57baf8d5e2682 https://git.kernel.org/stable/c/22a1f8a5b56ba93d3e8b7a1dafa24e01c8bb48ba https://git.kernel.org/stable/c/fac3c9f7784e8184c0338e9f0877b81e55d3ef1c https://git.kernel.org/stable/c/894cd5f5fd9061983445bbd1fa3d81be4 •

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 •
