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 •

https://notcve.org/view.php?id=CVE-2024-49973
In the Linux kernel, the following vulnerability has been resolved: r8169: add tally counter fields added with RTL8125 RTL8125 added fields to the tally counter, what may result in the chip dma'ing these new fields to unallocated memory. Therefore make sure that the allocated memory area is big enough to hold all of the tally counter values, even if we use only parts of it. • https://git.kernel.org/stable/c/f1bce4ad2f1cee6759711904b9fffe4a3dd8af87 https://git.kernel.org/stable/c/991e8b0bab669b7d06927c3e442b3352532e8581 https://git.kernel.org/stable/c/21950321ad33d7613b1453f4c503d7b1871deb61 https://git.kernel.org/stable/c/fe44b3bfbf0c74df5712f44458689d0eccccf47d https://git.kernel.org/stable/c/1c723d785adb711496bc64c24240f952f4faaabf https://git.kernel.org/stable/c/92bc8647b4d65f4d4bf8afdb206321c1bc55a486 https://git.kernel.org/stable/c/585c048d15ed559f20cb94c8fa2f30077efa4fbc https://git.kernel.org/stable/c/ced8e8b8f40accfcce4a2bbd8b150aa76 •

https://notcve.org/view.php?id=CVE-2024-49970
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Implement bounds check for stream encoder creation in DCN401 'stream_enc_regs' array is an array of dcn10_stream_enc_registers structures. The array is initialized with four elements, corresponding to the four calls to stream_enc_regs() in the array initializer. This means that valid indices for this array are 0, 1, 2, and 3. The error message 'stream_enc_regs' 4 <= 5 below, is indicating that there is an attempt to access this array with an index of 5, which is out of bounds. This could lead to undefined behavior Here, eng_id is used as an index to access the stream_enc_regs array. If eng_id is 5, this would result in an out-of-bounds access on the stream_enc_regs array.
