fkie_cve-2024-43854

In the Linux kernel, the following vulnerability has been resolved:

block: initialize integrity buffer to zero before writing it to media

Metadata added by bio_integrity_prep is using plain kmalloc, which leads to random kernel memory being written media. For PI metadata this is limited to the app tag that isn't used by kernel generated metadata, but for non-PI metadata the entire buffer leaks kernel memory.

Fix this by adding the __GFP_ZERO flag to allocations for writes.

OESA-2024-2106 — kernel security update

Affected: openEuler:22.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): In the Linux kernel, the following vulnerability has been resolved: ibmvnic: don't release napi in __ibmvnic_open() If __ibmvnic_open() encounters an error such as when setting link state, it calls release_resources() which frees the napi structures needlessly. Instead, have __ibmvnic_open() only clean up the work it did so far (i.e. disable napi and irqs) and leave the rest to the callers. If caller of __ibmvnic_open() is ibmvnic_open(), it should release the resources immediately. If the caller is do_reset() or do_hard_reset(), they will release the resources on the next reset. This fixes following crash that occurred when running the drmgr command several times to add/remove a vnic interface: [102056] ibmvnic 30000003 env3: Disabling rx_scrq[6] irq [102056] ibmvnic 30000003 env3: Disabling rx_scrq[7] irq [102056] ibmvnic 30000003 env3: Replenished 8 pools Kernel attempted to read user page (10) - exploit attempt?
