Vulnerabilidades

In the Linux kernel, the following vulnerability has been resolved: spi: Add NULL check for spi_get_device_id() in spi_get_device_match_data() Prevent NULL pointer dereference when spi_get_device_id() returns NULL, which can happen when using driver_override without matching SPI ID entry.

In the Linux kernel, the following vulnerability has been resolved: tls: reject the combination of TLS and sockmap TLS and sockmap (BPF psock) integration hides a lot of latent bugs. Bugs which may be more or less relevant for real users but they are definitely exploitable. We could not find anyone actively using this…

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Let driver decide buffer size at AMDKFD_IOC_GET_DMABUF_INFO ioctl amdkfd driver needs allocate buffer to return bo metadata to user space. The buffer size is controlled by user currently. It is a potential security issue that hostile value…

In the Linux kernel, the following vulnerability has been resolved: PCI: plda: Protect root bus removal with rescan lock Hold the pci_rescan_remove_lock lock while stopping and removing a root bus to avoid racing with concurrent rescan or hotplug operations triggered via sysfs. Such races may lead to use-after-free…

In the Linux kernel, the following vulnerability has been resolved: perf: Fix addr_filter_ranges lifetime Lee Jia Jie reported that since event::addr_filter_ranges is used under RCU, it should be RCU freed.

In the Linux kernel, the following vulnerability has been resolved: f2fs: validate inline dentry name lengths before conversion Inline dentry conversion copies names out of the inline dentry area before checking that each recorded name length fits in the available filename slots. A corrupted image can therefore make…

In the Linux kernel, the following vulnerability has been resolved: net: au1000: move free_irq out of the close-time spinlocked section au1000_close() calls free_irq() while aup->lock is still held with spin_lock_irqsave(). free_irq() can sleep because it takes the IRQ descriptor request mutex, so it does not belong…

In the Linux kernel, the following vulnerability has been resolved: spi: core: Abort active target transfer on controller suspend When an SPI controller operating in target mode has a transfer in progress at the time of system suspend, the suspend path proceeds without aborting the ongoing transfer. This can leave the…

In the Linux kernel, the following vulnerability has been resolved: btrfs: tree-checker: validate INODE_REF's namelen [BUG] A crafted btrfs image can trigger the following crash: [CAUSE] TThe crafted image has the following corrupted INODE_REF item: The itemsize matches the namelen, but the namelen is 4096, way larger…

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix sd_ndr.data memory leak in ksmbd_vfs_set_sd_xattr ndr_encode_v4_ntacl() allocates sd_ndr.data via kzalloc() at entry. If any subsequent ndr_write_*() call returns error during encoding, the allocated sd_ndr.data won't be freed and causes…

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Fix acl.sd_buf memory leak and invalid sd_size error handling

In the Linux kernel, the following vulnerability has been resolved: cachefiles: Fix double fput Fix a double fput() in error handling in cachefiles_create_tmpfile().

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: flush pending RCU callbacks on module unload Call rcu_barrier() in module exit to wait for outstanding call_rcu() callbacks before freeing module text, preventing late callback execution in freed memory. (cherry picked from commit…

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: caiaq: validate EP1 reply lengths usb_ep1_command_reply_dispatch() uses buf[0] as a command byte and then reads command-specific fixed items from the same URB buffer. Several paths use buf + 1, buf[1], buf[2], or buf + 3 without first…

In the Linux kernel, the following vulnerability has been resolved: wifi: rsi: avoid reading TKIP MIC keys for non-TKIP ciphers rsi_hal_load_key() copies tx_mic_key and rx_mic_key from data[16] and data[24] whenever key data is present. Those offsets are only part of the 32-byte TKIP key layout. Shorter keys used by…

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: validate assoc response length before status and IE access cfg80211_rx_assoc_resp() initialises the status and response-IE fields of cfg80211_connect_resp_params from the management frame before proving that the frame is long enough…

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: validate rx/tx MLME callback frame lengths before access cfg80211_rx_mlme_mgmt() and cfg80211_tx_mlme_mgmt() call tracepoints before rejecting frames shorter than the frame-control field. After that, they only require len >= 2 before…

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: ibss: wait for in-flight TX on disconnect While leaving an IBSS in ieee80211_ibss_disconnect() mac80211 flushes stations, turns the carrier off and immediately tells the driver to leave as well. While there may be synchronize_net() in…

In the Linux kernel, the following vulnerability has been resolved: wifi: libipw: fix key index receive bound checks libipw_rx() reads skb->data[hdrlen + 3] to extract the WEP key index in both the software-decrypt key selection path and the hardware-decrypted IV/ICV strip path. In both places the existing guard only…

In the Linux kernel, the following vulnerability has been resolved: wifi: rsi: validate beacon length before fixed buffer copy rsi_prepare_beacon() copies the mac80211 beacon frame after FRAME_DESC_SZ into a management skb whose usable tailroom may be smaller than MAX_MGMT_PKT_SIZE after alignment. Validate the beacon…

In the Linux kernel, the following vulnerability has been resolved: smb/client: zero-initialize stack-allocated cifs_open_info_data Stack-allocated cifs_open_info_data may contain random data. This can make some fields have wrong value if they are not set later.
