CVE-2024-43849 – soc: qcom: pdr: protect locator_addr with the main mutex
https://notcve.org/view.php?id=CVE-2024-43849
In the Linux kernel, the following vulnerability has been resolved: soc: qcom: pdr: protect locator_addr with the main mutex If the service locator server is restarted fast enough, the PDR can rewrite locator_addr fields concurrently. Protect them by placing modification of those fields under the main pdr->lock. • https://git.kernel.org/stable/c/fbe639b44a82755d639df1c5d147c93f02ac5a0f https://git.kernel.org/stable/c/eab05737ee22216250fe20d27f5a596da5ea6eb7 https://git.kernel.org/stable/c/d0870c4847e77a49c2f91bb2a8e0fa3c1f8dea5c https://git.kernel.org/stable/c/475a77fb3f0e1d527f56c60b79f5879661df5b80 https://git.kernel.org/stable/c/3e815626d73e05152a8142f6e44aecc4133e6e08 https://git.kernel.org/stable/c/8543269567e2fb3d976a8255c5e348aed14f98bc https://git.kernel.org/stable/c/107924c14e3ddd85119ca43c26a4ee1056fa9b84 •

CVE-2024-43846 – lib: objagg: Fix general protection fault
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.

CVE-2024-43842 – wifi: rtw89: Fix array index mistake in rtw89_sta_info_get_iter()
https://notcve.org/view.php?id=CVE-2024-43842
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'. Found by Linux Verification Center (linuxtesting.org) with SVACE. • https://git.kernel.org/stable/c/e3ec7017f6a20d12ddd9fe23d345ebb7b8c104dd https://git.kernel.org/stable/c/a2a095c08b95372d6d0c5819b77f071af5e75366 https://git.kernel.org/stable/c/7a0edc3d83aff3a48813d78c9cad9daf38decc74 https://git.kernel.org/stable/c/96ae4de5bc4c8ba39fd072369398f59495b73f58 https://git.kernel.org/stable/c/85099c7ce4f9e64c66aa397cd9a37473637ab891 •

CVE-2024-43841 – wifi: virt_wifi: avoid reporting connection success with wrong SSID
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 •

CVE-2024-43840 – bpf, arm64: Fix trampoline for BPF_TRAMP_F_CALL_ORIG
https://notcve.org/view.php?id=CVE-2024-43840
In the Linux kernel, the following vulnerability has been resolved: bpf, arm64: Fix trampoline for BPF_TRAMP_F_CALL_ORIG When BPF_TRAMP_F_CALL_ORIG is set, the trampoline calls __bpf_tramp_enter() and __bpf_tramp_exit() functions, passing them the struct bpf_tramp_image *im pointer as an argument in R0. The trampoline generation code uses emit_addr_mov_i64() to emit instructions for moving the bpf_tramp_image address into R0, but emit_addr_mov_i64() assumes the address to be in the vmalloc() space and uses only 48 bits. Because bpf_tramp_image is allocated using kzalloc(), its address can use more than 48-bits, in this case the trampoline will pass an invalid address to __bpf_tramp_enter/exit() causing a kernel crash. Fix this by using emit_a64_mov_i64() in place of emit_addr_mov_i64() as it can work with addresses that are greater than 48-bits. • https://git.kernel.org/stable/c/efc9909fdce00a827a37609628223cd45bf95d0b https://git.kernel.org/stable/c/6d218fcc707d6b2c3616b6cd24b948fd4825cfec https://git.kernel.org/stable/c/19d3c179a37730caf600a97fed3794feac2b197b •
