In the Linux kernel, the following vulnerability has been resolved: net: mana: Fix TX CQE error handling For an unknown TX CQE error type (probably from a newer hardware), still free the SKB, update the queue tail, etc., otherwise the accounting will be wrong. Also, TX errors can be triggered by injecting corrupted packets, so replace the WARN_ONCE to ratelimited error logging. • https://git.kernel.org/stable/c/ca9c54d2d6a5ab2430c4eda364c77125d62e5e0f https://git.kernel.org/stable/c/b67d7b1bfc46d05c1a58b172516454698e8d5004 https://git.kernel.org/stable/c/a910e0f6304726da30a212feecec65cb97ff7a80 https://git.kernel.org/stable/c/b2b000069a4c307b09548dc2243f31f3ca0eac9c •

https://notcve.org/view.php?id=CVE-2023-52531
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: Fix a memory corruption issue A few lines above, space is kzalloc()'ed for: sizeof(struct iwl_nvm_data) + sizeof(struct ieee80211_channel) + sizeof(struct ieee80211_rate) 'mvm->nvm_data' is a 'struct iwl_nvm_data', so it is fine. At the end of this structure, there is the 'channels' flex array. Each element is of type 'struct ieee80211_channel'. So only 1 element is allocated in this array. When doing: mvm->nvm_data->bands[0].channels = mvm->nvm_data->channels; We point at the first element of the 'channels' flex array. So this is fine. However, when doing: mvm->nvm_data->bands[0].bitrates = (void *)((u8 *)mvm->nvm_data->channels + 1); because of the "(u8 *)" cast, we add only 1 to the address of the beginning of the flex array. It is likely that we want point at the 'struct ieee80211_rate' allocated just after. Remove the spurious casting so that the pointer arithmetic works as expected. • https://git.kernel.org/stable/c/8ca151b568b67a7b72dcfc6ee6ea7c107ddd795c https://git.kernel.org/stable/c/7c8faa31080342aec4903c9acb20caf82fcca1ef https://git.kernel.org/stable/c/6b3223449c959a8be94a1f042288059e40fcccb0 https://git.kernel.org/stable/c/f06cdd8d4ba5252986f51f80cc30263636397128 https://git.kernel.org/stable/c/8ba438ef3cacc4808a63ed0ce24d4f0942cfe55d •
CVSS: 5.8EPSS: 0%CPEs: 12EXPL: 0CVE-2023-52530 – wifi: mac80211: fix potential key use-after-free
https://notcve.org/view.php?id=CVE-2023-52530
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix potential key use-after-free When ieee80211_key_link() is called by ieee80211_gtk_rekey_add() but returns 0 due to KRACK protection (identical key reinstall), ieee80211_gtk_rekey_add() will still return a pointer into the key, in a potential use-after-free. This normally doesn't happen since it's only called by iwlwifi in case of WoWLAN rekey offload which has its own KRACK protection, but still better to fix, do that by returning an error code and converting that to success on the cfg80211 boundary only, leaving the error for bad callers of ieee80211_gtk_rekey_add(). A use-after-free flaw was found in the Linux kernel’s IEEE 802.11 networking stack implementation functionality, used by Wifi, in how a user triggers the error path of the ieee80211_gtk_rekey_add function. This flaw allows a local user to crash the system. • https://git.kernel.org/stable/c/fdf7cb4185b60c68e1a75e61691c4afdc15dea0e https://git.kernel.org/stable/c/ef810e7c3d2a8fb3bbd23726599c487c30ea747e https://git.kernel.org/stable/c/a0a8a11d1630cd648dc1ce86da620b4e240e0315 https://git.kernel.org/stable/c/6891c6fd2a500d1f39d1426765f610bdc2c2a39d https://git.kernel.org/stable/c/003aa22c9619b49efe950aca3aebd1235a04940d https://git.kernel.org/stable/c/6440f0ee8a1779f53526bccb9de00914daeb9094 https://git.kernel.org/stable/c/2586fa0007dc6b7745da14250be7e3aae706b128 https://git.kernel.org/stable/c/a9ab1b2e30e898440a22d7b1d7a5b0b7c • CWE-416: Use After Free •
