In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix invalid memory access while processing fragmented packets The monitor ring and the reo reinject ring share the same ring mask index. When the driver receives an interrupt for the reo reinject ring, the monitor ring is also processed, leading to invalid memory access. Since monitor support is not yet enabled in ath12k, the ring mask for the monitor ring should be removed.

https://notcve.org/view.php?id=CVE-2024-43846
In the Linux kernel, the following vulnerability has been resolved: lib: objagg: Fix general protection fault The library supports aggregation of objects into other objects only if the parent object does not have a parent itself. That is, nesting is not supported. Aggregation happens in two cases: Without and with hints, where hints are a pre-computed recommendation on how to aggregate the provided objects. Nesting is not possible in the first case due to a check that prevents it, but in the second case there is no check because the assumption is that nesting cannot happen when creating objects based on hints. The violation of this assumption leads to various warnings and eventually to a general protection fault [1]. Before fixing the root cause, error out when nesting happens and warn.

https://notcve.org/view.php?id=CVE-2024-43845
In the Linux kernel, the following vulnerability has been resolved: udf: Fix bogus checksum computation in udf_rename() Syzbot reports uninitialized memory access in udf_rename() when updating checksum of '..' directory entry of a moved directory. This is indeed true as we pass on-stack diriter.fi to the udf_update_tag() and because that has only struct fileIdentDesc included in it and not the impUse or name fields, the checksumming function is going to checksum random stack contents beyond the end of the structure. This is actually harmless because the following udf_fiiter_write_fi() will recompute the checksum from on-disk buffers where everything is properly included. So all that is needed is just removing the bogus calculation. • https://git.kernel.org/stable/c/9616d00140a1cdf0bfa557019b36923dc7796942 https://git.kernel.org/stable/c/e9109a92d2a95889498bed3719cd2318892171a2 https://git.kernel.org/stable/c/c996b570305e7a6910c2ce4cdcd4c22757ffe241 https://git.kernel.org/stable/c/fe2ead240c31e8d158713beca9d0681a6e6a53ab https://git.kernel.org/stable/c/40d7b3ed52449d36143bab8d3e70926aa61a60f4 https://git.kernel.org/stable/c/27ab33854873e6fb958cb074681a0107cc2ecc4c https://git.kernel.org/stable/c/9c439311c13fc6faab1921441165c9b8b500c83b •

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: Fix array index mistake in rtw89_sta_info_get_iter() In rtw89_sta_info_get_iter() 'status->he_gi' is compared to array size. But then 'rate->he_gi' is used as array index instead of 'status->he_gi'. This can lead to go beyond array boundaries in case of 'rate->he_gi' is not equal to 'status->he_gi' and is bigger than array size. Looks like "copy-paste" mistake. Fix this mistake by replacing 'rate->he_gi' with 'status->he_gi'.

https://notcve.org/view.php?id=CVE-2024-43841
In the Linux kernel, the following vulnerability has been resolved: wifi: virt_wifi: avoid reporting connection success with wrong SSID When user issues a connection with a different SSID than the one virt_wifi has advertised, the __cfg80211_connect_result() will trigger the warning: WARN_ON(bss_not_found). The issue is because the connection code in virt_wifi does not check the SSID from user space (it only checks the BSSID), and virt_wifi will call cfg80211_connect_result() with WLAN_STATUS_SUCCESS even if the SSID is different from the one virt_wifi has advertised. Eventually cfg80211 won't be able to find the cfg80211_bss and generate the warning. Fixed it by checking the SSID (from user space) in the connection code. • https://git.kernel.org/stable/c/c7cdba31ed8b87526db978976392802d3f93110c https://git.kernel.org/stable/c/994fc2164a03200c3bf42fb45b3d49d9d6d33a4d https://git.kernel.org/stable/c/05c4488a0e446c6ccde9f22b573950665e1cd414 https://git.kernel.org/stable/c/93e898a264b4e0a475552ba9f99a016eb43ef942 https://git.kernel.org/stable/c/d3cc85a10abc8eae48988336cdd3689ab92581b3 https://git.kernel.org/stable/c/36e92b5edc8e0daa18e9325674313802ce3fbc29 https://git.kernel.org/stable/c/416d3c1538df005195721a200b0371d39636e05d https://git.kernel.org/stable/c/b5d14b0c6716fad7f0c94ac6e1d6f60a4 •
