Vulnerabilidades

In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Fix FRMR set pinned push error path Add destruction of FRMR handles in case the push to the pool fails. This prevents resources leak in case pool page allocation fails.

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix undefined shift of user RQ WQE size set_rq_size() computes the RQ WQE size as "1 << rq_wqe_shift" based on the user-provided rq_wqe_shift, which is only checked to be greater than 32, so shifts of 32 are still accepted. A shift of 31…

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Release the HW‑provided UAR index rather than the SW one Free the UAR index returned by the hardware.

In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: hdac_hdmi: Validate written enum value hdac_hdmi_set_pin_port_mux() uses the written enum value to index the texts array before calling snd_soc_dapm_put_enum_double(), which validates that the value is within the enum item range. An…

In the Linux kernel, the following vulnerability has been resolved: ASoC: fsl: fsl_audmix: Validate written enum values fsl_audmix_put_mix_clk_src() and fsl_audmix_put_out_src() convert the user-provided enum item with snd_soc_enum_item_to_val() before checking whether the item is within the enum's item count. The…

In the Linux kernel, the following vulnerability has been resolved: ASoC: tegra: tegra210_ahub: Validate written enum value tegra_ahub_put_value_enum() reads e->values[item[0]] before checking whether item[0] is within the enum item range. The existing check therefore happens too late to prevent an out-of-range read…

In the Linux kernel, the following vulnerability has been resolved: net/sched: cls_flow: Dont expose folded kernel pointers The flow classifier falls back to addr_fold() for fields that are missing from packet headers. In map mode, userspace controls mask, xor, rshift, addend and divisor, and can observe the resulting…

In the Linux kernel, the following vulnerability has been resolved: net: fib_rules: Don't dump dying fib_rule in fib_rules_dump(). rocker_router_fib_event() calls fib_rule_get() during RCU dump. If the fib_rule is dying, refcount_inc() will complain about it. Let's call refcount_inc_not_zero() in fib_rules_dump().

In the Linux kernel, the following vulnerability has been resolved: sctp: validate embedded address parameter length sctp_verify_asconf() and sctp_verify_param() only validate ADD_IP, DEL_IP, and SET_PRIMARY parameters against a fixed minimum size of sizeof(struct sctp_addip_param) + sizeof(struct sctp_paramhdr). This…

In the Linux kernel, the following vulnerability has been resolved: net: pfcp: allocate per-cpu tstats for PFCP netdevs PFCP uses dev_get_tstats64() as its ndo_get_stats64 callback, but pfcp_link_setup() does not request NETDEV_PCPU_STAT_TSTATS. The net core therefore leaves dev->tstats NULL for PFCP devices. Creating…

In the Linux kernel, the following vulnerability has been resolved: net: Stop leased rxq before uninstalling its memory provider netif_rxq_cleanup_unlease() tears down the memory provider that was installed on a physical RX queue through a netkit queue lease. It currently revokes the provider's DMA mappings before…

In the Linux kernel, the following vulnerability has been resolved: net/sched: sch_hfsc: Don't make class passive twice update_vf() is called from two places for the same class during a single dequeue when the class's child qdisc (e.g. codel/fq_codel) drops its last packets while dequeuing: On the second call the…

In the Linux kernel, the following vulnerability has been resolved: tipc: require net admin for TIPCv2 netlink mutators TIPCv2 registers mutating generic-netlink operations without admin permission flags. Generic netlink only checks CAP_NET_ADMIN when an operation sets GENL_ADMIN_PERM or GENL_UNS_ADMIN_PERM, so a…

In the Linux kernel, the following vulnerability has been resolved: tipc: prevent snt_unacked underflow on CONN_ACK tipc_sk_conn_proto_rcv() subtracts the peer-supplied connection ack count from the unsigned 16-bit send counter snt_unacked without checking that it does not exceed the number of messages actually…

In the Linux kernel, the following vulnerability has been resolved: tipc: reject inverted service ranges from peer bindings tipc_update_nametbl() inserts a binding advertised by a peer node using the lower and upper service-range bounds taken directly from the wire, without checking that lower <= upper. The local bind…

In the Linux kernel, the following vulnerability has been resolved: crypto: marvell/octeontx - fix DMA cleanup using wrong loop index The sg_cleanup path used list[i] instead of list[j] when unmapping DMA buffers, leaking successfully mapped entries and repeatedly unmapping the failed one.

In the Linux kernel, the following vulnerability has been resolved: crypto: cavium/cpt - fix DMA cleanup using wrong loop index The sg_cleanup error path used list[i] instead of list[j] when unmapping DMA buffers, leaking successfully mapped entries and repeatedly unmapping the failed one.

In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: Fix kernel heap address leak in bounce_error_event() The comment above bounce_error_event() documents that user clients should receive SNDRV_SEQ_EVENT_BOUNCE with the original event embedded as variable-length data, while kernel clients…

In the Linux kernel, the following vulnerability has been resolved: iommu/dma-iommu: Fix wrong scatterlist length assignment in P2PDMA path In iommu_dma_map_sg(), when handling PCI P2PDMA cases, the DMA length of the current scatterlist segment `s` is incorrectly assigned from the head entry `sg->length` instead of…

In the Linux kernel, the following vulnerability has been resolved: spi: xilinx: use FIFO occupancy register to determine buffer size The method the driver uses to determine the size of the FIFO has a problem. What it currently does is this: It stops the SPI hardware and writes to the TX FIFO register until TX FIFO…

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Fix out-of-bounds access in cxl_cancel_auto_attach() In cxl_cancel_auto_attach(), it assumes cxled->pos is a valid index for accessing p->targets[]. However, cxled->pos can be set to negative errno in cxl_region_sort_targets() if…

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Fill first free targets[] slot during auto-discovery Any invalid endpoint decoder pointer in the target array of an active region is not allowed by cxl driver. This means cxl driver always assumes the first p->nr_targets entries of the…

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Block region delete during region creation Expand the range lock, rename it "regions_lock", to disable region deletion in the critical period between construct_region() and attach_target(), as well as the period between device_add() and…

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Resolve region deletion races Sungwoo noticed that the sysfs trigger to delete a region may try to delete a region multiple times. It also has no exclusion relative to the kernel releasing the region via CXL root device teardown. Instead…

In the Linux kernel, the following vulnerability has been resolved: power: supply: core: fix supplied_from allocations If dts property power-supplies has multiple values, then accessing to psy->supplied_from[i-1] in __power_supply_populate_supplied_from will overrun supplied_from array.
