DATE CVE VULNERABILITY TITLE RISK
2024-10-21 CVE-2024-47757 Out-of-bounds Read vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix potential oob read in nilfs_btree_check_delete() The function nilfs_btree_check_delete(), which checks whether degeneration to direct mapping occurs before deleting a b-tree entry, causes memory access outside the block buffer when retrieving the maximum key if the root node has no entries. This does not usually happen because b-tree mappings with 0 child nodes are never created by mkfs.nilfs2 or nilfs2 itself.

2024-10-21 CVE-2024-49850 NULL Pointer Dereference vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: bpf: correctly handle malformed BPF_CORE_TYPE_ID_LOCAL relos In case of malformed relocation record of kind BPF_CORE_TYPE_ID_LOCAL referencing a non-existing BTF type, function bpf_core_calc_relo_insn would cause a null pointer deference. Fix this by adding a proper check upper in call stack, as malformed relocation records could be passed from user space. Simplest reproducer is a program: r0 = 0 exit With a single relocation record: .insn_off = 0, /* patch first instruction */ .type_id = 100500, /* this type id does not exist */ .access_str_off = 6, /* offset of string "0" */ .kind = BPF_CORE_TYPE_ID_LOCAL, See the link for original reproducer or next commit for a test case.

2024-10-21 CVE-2024-49853 Double Free vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Fix double free in OPTEE transport Channels can be shared between protocols, avoid freeing the same channel descriptors twice when unloading the stack.

2024-10-21 CVE-2024-49854 Use After Free vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: block, bfq: fix uaf for accessing waker_bfqq after splitting After commit 42c306ed7233 ("block, bfq: don't break merge chain in bfq_split_bfqq()"), if the current procress is the last holder of bfqq, the bfqq can be freed after bfq_split_bfqq().

2024-10-21 CVE-2024-49855 Use After Free vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: nbd: fix race between timeout and normal completion If request timetout is handled by nbd_requeue_cmd(), normal completion has to be stopped for avoiding to complete this requeued request, other use-after-free can be triggered. Fix the race by clearing NBD_CMD_INFLIGHT in nbd_requeue_cmd(), meantime make sure that cmd->lock is grabbed for clearing the flag and the requeue.

2024-10-21 CVE-2024-49856 Infinite Loop vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: x86/sgx: Fix deadlock in SGX NUMA node search When the current node doesn't have an EPC section configured by firmware and all other EPC sections are used up, CPU can get stuck inside the while loop that looks for an available EPC page from remote nodes indefinitely, leading to a soft lockup.

2024-10-21 CVE-2024-49857 NULL Pointer Dereference vulnerability in Linux Kernel 6.11
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: set the cipher for secured NDP ranging The cipher pointer is not set, but is derefereced trying to set its content, which leads to a NULL pointer dereference. Fix it by pointing to the cipher parameter before dereferencing.

2024-10-21 CVE-2024-49858 Unspecified vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: efistub/tpm: Use ACPI reclaim memory for event log to avoid corruption The TPM event log table is a Linux specific construct, where the data produced by the GetEventLog() boot service is cached in memory, and passed on to the OS using an EFI configuration table. The use of EFI_LOADER_DATA here results in the region being left unreserved in the E820 memory map constructed by the EFI stub, and this is the memory description that is passed on to the incoming kernel by kexec, which is therefore unaware that the region should be reserved. Even though the utility of the TPM2 event log after a kexec is questionable, any corruption might send the parsing code off into the weeds and crash the kernel.
