https://notcve.org/view.php?id=CVE-2024-42151
In the Linux kernel, the following vulnerability has been resolved: bpf: mark bpf_dummy_struct_ops.test_1 parameter as nullable Test case dummy_st_ops/dummy_init_ret_value passes NULL as the first parameter of the test_1() function. Mark this parameter as nullable to make verifier aware of such possibility. Otherwise, NULL check in the test_1() code: SEC("struct_ops/test_1") int BPF_PROG(test_1, struct bpf_dummy_ops_state *state) { if (!state) return ...; ... access state ... } Might be removed by verifier, thus triggering NULL pointer dereference under certain conditions. • https://git.kernel.org/stable/c/7f79097b0de97a486b137b750d7dd7b20b519d23 https://git.kernel.org/stable/c/1479eaff1f16983d8fda7c5a08a586c21891087d •

https://notcve.org/view.php?id=CVE-2024-42148
In the Linux kernel, the following vulnerability has been resolved: bnx2x: Fix multiple UBSAN array-index-out-of-bounds Fix UBSAN warnings that occur when using a system with 32 physical cpu cores or more, or when the user defines a number of Ethernet queues greater than or equal to FP_SB_MAX_E1x using the num_queues module parameter. Currently there is a read/write out of bounds that occurs on the array "struct stats_query_entry query" present inside the "bnx2x_fw_stats_req" struct in "drivers/net/ethernet/broadcom/bnx2x/bnx2x.h". Looking at the definition of the "struct stats_query_entry query" array: struct stats_query_entry query[FP_SB_MAX_E1x+ BNX2X_FIRST_QUEUE_QUERY_IDX]; FP_SB_MAX_E1x is defined as the maximum number of fast path interrupts and has a value of 16, while BNX2X_FIRST_QUEUE_QUERY_IDX has a value of 3 meaning the array has a total size of 19. Since accesses to "struct stats_query_entry query" are offset-ted by BNX2X_FIRST_QUEUE_QUERY_IDX, that means that the total number of Ethernet queues should not exceed FP_SB_MAX_E1x (16). However one of these queues is reserved for FCOE and thus the number of Ethernet queues should be set to [FP_SB_MAX_E1x -1] (15) if FCOE is enabled or [FP_SB_MAX_E1x] (16) if it is not. This is also described in a comment in the source code in drivers/net/ethernet/broadcom/bnx2x/bnx2x.h just above the Macro definition of FP_SB_MAX_E1x. Below is the part of this explanation that it important for this patch /* * The total number of L2 queues, MSIX vectors and HW contexts (CIDs) is * control by the number of fast-path status blocks supported by the * device (HW/FW). Each fast-path status block (FP-SB) aka non-default * status block represents an independent interrupts context that can * serve a regular L2 networking queue. However special L2 queues such * as the FCoE queue do not require a FP-SB and other components like * the CNIC may consume FP-SB reducing the number of possible L2 queues * * If the maximum number of FP-SB available is X then: * a. • https://git.kernel.org/stable/c/50f0a562f8cc9ed9d9f7f7380434c3c8646172d5 https://git.kernel.org/stable/c/cfb04472ce33bee2579caf4dc9f4242522f6e26e https://git.kernel.org/stable/c/cbe53087026ad929cd3950508397e8892a6a2a0f https://git.kernel.org/stable/c/8b17cec33892a66bbd71f8d9a70a45e2072ae84f https://git.kernel.org/stable/c/0edae06b4c227bcfaf3ce21208d49191e1009d3b https://git.kernel.org/stable/c/9504a1550686f53b0bab4cab31d435383b1ee2ce https://git.kernel.org/stable/c/f1313ea92f82451923e28ab45a4aaa0e70e80b98 https://git.kernel.org/stable/c/b9ea38e767459111a511ed4fb74abc37d •

https://notcve.org/view.php?id=CVE-2024-42147
In the Linux kernel, the following vulnerability has been resolved: crypto: hisilicon/debugfs - Fix debugfs uninit process issue During the zip probe process, the debugfs failure does not stop the probe. When debugfs initialization fails, jumping to the error branch will also release regs, in addition to its own rollback operation. As a result, it may be released repeatedly during the regs uninit process. Therefore, the null check needs to be added to the regs uninit process. • https://git.kernel.org/stable/c/eda60520cfe3aba9f088c68ebd5bcbca9fc6ac3c https://git.kernel.org/stable/c/7fc8d9a525b5c3f8dfa5ed50901e764d8ede7e1e https://git.kernel.org/stable/c/e0a2d2df9ba7bd6bd7e0a9b6a5e3894f7e8445b3 https://git.kernel.org/stable/c/8be0913389718e8d27c4f1d4537b5e1b99ed7739 •

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-42145 – IB/core: Implement a limit on UMAD receive List
https://notcve.org/view.php?id=CVE-2024-42145
In the Linux kernel, the following vulnerability has been resolved: IB/core: Implement a limit on UMAD receive List The existing behavior of ib_umad, which maintains received MAD packets in an unbounded list, poses a risk of uncontrolled growth. As user-space applications extract packets from this list, the rate of extraction may not match the rate of incoming packets, leading to potential list overflow. To address this, we introduce a limit to the size of the list. After considering typical scenarios, such as OpenSM processing, which can handle approximately 100k packets per second, and the 1-second retry timeout for most packets, we set the list size limit to 200k. Packets received beyond this limit are dropped, assuming they are likely timed out by the time they are handled by user-space. Notably, packets queued on the receive list due to reasons like timed-out sends are preserved even when the list is full. • https://git.kernel.org/stable/c/1288cf1cceb0e6df276e182f5412370fb4169bcb https://git.kernel.org/stable/c/b4913702419d064ec4c4bbf7270643c95cc89a1b https://git.kernel.org/stable/c/62349fbf86b5e13b02721bdadf98c29afd1e7b5f https://git.kernel.org/stable/c/d73cb8862e4d6760ccc94d3b57b9ef6271400607 https://git.kernel.org/stable/c/63d202d948bb6d3a28cd8e8b96b160fa53e18baa https://git.kernel.org/stable/c/b8c5f635997f49c625178d1a0cb32a80ed33abe6 https://git.kernel.org/stable/c/a6627fba793cc75b7365d9504a0095fb2902dda4 https://git.kernel.org/stable/c/ca0b44e20a6f3032224599f02e7c8fb49 •
