In the Linux kernel, the following vulnerability has been resolved: drm/xe/hdcp: Check GSC structure validity Sometimes xe_gsc is not initialized when checked at HDCP capability check. Add gsc structure check to avoid null pointer error. • https://git.kernel.org/stable/c/c940627857eedca8407b84b40ceb4252b100d291 https://git.kernel.org/stable/c/7266a424b1e502745170322e3c27f697d12de627 https://git.kernel.org/stable/c/b4224f6bae3801d589f815672ec62800a1501b0d •

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.

https://notcve.org/view.php?id=CVE-2024-49988
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 •

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: 3EXPL: 0CVE-2024-49974 – NFSD: Limit the number of concurrent async COPY operations
https://notcve.org/view.php?id=CVE-2024-49974
In the Linux kernel, the following vulnerability has been resolved: NFSD: Limit the number of concurrent async COPY operations Nothing appears to limit the number of concurrent async COPY operations that clients can start. In addition, AFAICT each async COPY can copy an unlimited number of 4MB chunks, so can run for a long time. Thus IMO async COPY can become a DoS vector. Add a restriction mechanism that bounds the number of concurrent background COPY operations. Start simple and try to be fair -- this patch implements a per-namespace limit. An async COPY request that occurs while this limit is exceeded gets NFS4ERR_DELAY. The requesting client can choose to send the request again after a delay or fall back to a traditional read/write style copy. If there is need to make the mechanism more sophisticated, we can visit that in future patches. • https://git.kernel.org/stable/c/b4e21431a0db4854b5023cd5af001be557e6c3db https://git.kernel.org/stable/c/6a488ad7745b8f64625c6d3a24ce7e448e83f11b https://git.kernel.org/stable/c/aadc3bbea163b6caaaebfdd2b6c4667fbc726752 •
