CVE-2024-45010 – mptcp: pm: only mark 'subflow' endp as available
https://notcve.org/view.php?id=CVE-2024-45010
In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: only mark 'subflow' endp as available Adding the following warning ... WARN_ON_ONCE(msk->pm.local_addr_used == 0) ... before decrementing the local_addr_used counter helped to find a bug when running the "remove single address" subtest from the mptcp_join.sh selftests. Removing a 'signal' endpoint will trigger the removal of all subflows linked to this endpoint via mptcp_pm_nl_rm_addr_or_subflow() with rm_type == MPTCP_MIB_RMSUBFLOW. This will decrement the local_addr_used counter, which is wrong in this case because this counter is linked to 'subflow' endpoints, and here it is a 'signal' endpoint that is being removed. Now, the counter is decremented, only if the ID is being used outside of mptcp_pm_nl_rm_addr_or_subflow(), only for 'subflow' endpoints, and if the ID is not 0 -- local_addr_used is not taking into account these ones. This marking of the ID as being available, and the decrement is done no matter if a subflow using this ID is currently available, because the subflow could have been closed before. • https://git.kernel.org/stable/c/06faa22710342bca5e9c249634199c650799fce6 https://git.kernel.org/stable/c/7fdc870d08960961408a44c569f20f50940e7d4f https://git.kernel.org/stable/c/43cf912b0b0fc7b4fd12cbc735d1f5afb8e1322d https://git.kernel.org/stable/c/9849cfc67383ceb167155186f8f8fe8a896b60b3 https://git.kernel.org/stable/c/322ea3778965da72862cca2a0c50253aacf65fe6 •

CVE-2024-45009 – mptcp: pm: only decrement add_addr_accepted for MPJ req
https://notcve.org/view.php?id=CVE-2024-45009
In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: only decrement add_addr_accepted for MPJ req Adding the following warning ... WARN_ON_ONCE(msk->pm.add_addr_accepted == 0) ... before decrementing the add_addr_accepted counter helped to find a bug when running the "remove single subflow" subtest from the mptcp_join.sh selftest. Removing a 'subflow' endpoint will first trigger a RM_ADDR, then the subflow closure. Before this patch, and upon the reception of the RM_ADDR, the other peer will then try to decrement this add_addr_accepted. That's not correct because the attached subflows have not been created upon the reception of an ADD_ADDR. A way to solve that is to decrement the counter only if the attached subflow was an MP_JOIN to a remote id that was not 0, and initiated by the host receiving the RM_ADDR. • https://git.kernel.org/stable/c/d0876b2284cf8b34dd214b2d0aa21071c345da59 https://git.kernel.org/stable/c/35b31f5549ede4070566b949781e83495906b43d https://git.kernel.org/stable/c/85b866e4c4e63a1d7afb58f1e24273caad03d0b7 https://git.kernel.org/stable/c/d20bf2c96d7ffd171299b32f562f70e5bf5dc608 https://git.kernel.org/stable/c/2060f1efab370b496c4903b840844ecaff324c3c https://git.kernel.org/stable/c/1c1f721375989579e46741f59523e39ec9b2a9bd •

CVE-2023-52916 – media: aspeed: Fix memory overwrite if timing is 1600x900
https://notcve.org/view.php?id=CVE-2023-52916
In the Linux kernel, the following vulnerability has been resolved: media: aspeed: Fix memory overwrite if timing is 1600x900 When capturing 1600x900, system could crash when system memory usage is tight. The way to reproduce this issue: 1. Use 1600x900 to display on host 2. Mount ISO through 'Virtual media' on OpenBMC's web 3. Run script as below on host to do sha continuously #!/bin/bash while [ [1] ]; do find /media -type f -printf '"%h/%f"\n' | xargs sha256sum done 4. • https://git.kernel.org/stable/c/c281355068bc258fd619c5aefd978595bede7bfe •

CVE-2023-52915 – media: dvb-usb-v2: af9035: Fix null-ptr-deref in af9035_i2c_master_xfer
https://notcve.org/view.php?id=CVE-2023-52915
In the Linux kernel, the following vulnerability has been resolved: media: dvb-usb-v2: af9035: Fix null-ptr-deref in af9035_i2c_master_xfer In af9035_i2c_master_xfer, msg is controlled by user. When msg[i].buf is null and msg[i].len is zero, former checks on msg[i].buf would be passed. Malicious data finally reach af9035_i2c_master_xfer. If accessing msg[i].buf[0] without sanity check, null ptr deref would happen. We add check on msg[i].len to prevent crash.
