CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2022-48805 – net: usb: ax88179_178a: Fix out-of-bounds accesses in RX fixup
https://notcve.org/view.php?id=CVE-2022-48805
In the Linux kernel, the following vulnerability has been resolved: net: usb: ax88179_178a: Fix out-of-bounds accesses in RX fixup ax88179_rx_fixup() contains several out-of-bounds accesses that can be triggered by a malicious (or defective) USB device, in particular: - The metadata array (hdr_off..hdr_off+2*pkt_cnt) can be out of bounds, causing OOB reads and (on big-endian systems) OOB endianness flips. - A packet can overlap the metadata array, causing a later OOB endianness flip to corrupt data used by a cloned SKB that has already been handed off into the network stack. - A packet SKB can be constructed whose tail is far beyond its end, causing out-of-bounds heap data to be considered part of the SKB's data. I have tested that this can be used by a malicious USB device to send a bogus ICMPv6 Echo Request and receive an ICMPv6 Echo Reply in response that contains random kernel heap data. It's probably also possible to get OOB writes from this on a little-endian system somehow - maybe by triggering skb_cow() via IP options processing -, but I haven't tested that. • https://git.kernel.org/stable/c/e2ca90c276e1fc410d7cd3c1a4eee245ec902a20 https://git.kernel.org/stable/c/711b6bf3fb052f0a6b5b3205d50e30c0c2980382 https://git.kernel.org/stable/c/63f0cfb36c1f1964a59ce544156677601e2d8740 https://git.kernel.org/stable/c/1668781ed24da43498799aa4f65714a7de201930 https://git.kernel.org/stable/c/a0fd5492ee769029a636f1fb521716b022b1423d https://git.kernel.org/stable/c/758290defe93a865a2880d10c5d5abd288b64b5d https://git.kernel.org/stable/c/ffd0393adcdcefab7e131488e10dcfde5e02d6eb https://git.kernel.org/stable/c/9681823f96a811268265f35307072ad80 •

https://notcve.org/view.php?id=CVE-2022-48804
In the Linux kernel, the following vulnerability has been resolved: vt_ioctl: fix array_index_nospec in vt_setactivate array_index_nospec ensures that an out-of-bounds value is set to zero on the transient path. Decreasing the value by one afterwards causes a transient integer underflow. vsa.console should be decreased first and then sanitized with array_index_nospec.
