https://notcve.org/view.php?id=CVE-2024-42150
In the Linux kernel, the following vulnerability has been resolved: net: txgbe: remove separate irq request for MSI and INTx When using MSI or INTx interrupts, request_irq() for pdev->irq will conflict with request_threaded_irq() for txgbe->misc.irq, to cause system crash. So remove txgbe_request_irq() for MSI/INTx case, and rename txgbe_request_msix_irqs() since it only request for queue irqs. Add wx->misc_irq_domain to determine whether the driver creates an IRQ domain and threaded request the IRQs. • https://git.kernel.org/stable/c/aefd013624a10f39b0bfaee8432a235128705380 https://git.kernel.org/stable/c/ffe8a87463c8bb885c42ed54540d06ed041e76dc https://git.kernel.org/stable/c/850103ebe6b062ee0ab0f6670205f861acc76ace https://git.kernel.org/stable/c/bd07a98178462e7a02ed2bf7dec90a00944c1da5 •
CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-42149 – fs: don't misleadingly warn during thaw operations
https://notcve.org/view.php?id=CVE-2024-42149
In the Linux kernel, the following vulnerability has been resolved: fs: don't misleadingly warn during thaw operations The block device may have been frozen before it was claimed by a filesystem. Concurrently another process might try to mount that frozen block device and has temporarily claimed the block device for that purpose causing a concurrent fs_bdev_thaw() to end up here. The mounter is already about to abort mounting because they still saw an elevanted bdev->bd_fsfreeze_count so get_bdev_super() will return NULL in that case. For example, P1 calls dm_suspend() which calls into bdev_freeze() before the block device has been claimed by the filesystem. This brings bdev->bd_fsfreeze_count to 1 and no call into fs_bdev_freeze() is required. Now P2 tries to mount that frozen block device. It claims it and checks bdev->bd_fsfreeze_count. • https://git.kernel.org/stable/c/49ef8832fb1a9e0da0020eb17480fd286433bc13 https://git.kernel.org/stable/c/25b1e3906e050d452427bc51620bb7f0a591373a https://git.kernel.org/stable/c/2ae4db5647d807efb6a87c09efaa6d1db9c905d7 •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-42148 – bnx2x: Fix multiple UBSAN array-index-out-of-bounds
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 •

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 •
