+Subject: Bluetooth: rfcomm: Fix null-ptr-deref in rfcomm_check_security
+Origin: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit?id=567c0411dc3b424fc7bd1e6109726d7ba32d4f73
+Bug-Debian-Security: https://security-tracker.debian.org/tracker/CVE-2024-22099
+
+[ Upstream commit 2535b848fa0f42ddff3e5255cf5e742c9b77bb26 ]
+
+During our fuzz testing of the connection and disconnection process at the
+RFCOMM layer, we discovered this bug. By comparing the packets from a
+normal connection and disconnection process with the testcase that
+triggered a KASAN report. We analyzed the cause of this bug as follows:
+
+1. In the packets captured during a normal connection, the host sends a
+`Read Encryption Key Size` type of `HCI_CMD` packet
+(Command Opcode: 0x1408) to the controller to inquire the length of
+encryption key.After receiving this packet, the controller immediately
+replies with a Command Completepacket (Event Code: 0x0e) to return the
+Encryption Key Size.
+
+2. In our fuzz test case, the timing of the controller's response to this
+packet was delayed to an unexpected point: after the RFCOMM and L2CAP
+layers had disconnected but before the HCI layer had disconnected.
+
+3. After receiving the Encryption Key Size Response at the time described
+in point 2, the host still called the rfcomm_check_security function.
+However, by this time `struct l2cap_conn *conn = l2cap_pi(sk)->chan->conn;`
+had already been released, and when the function executed
+`return hci_conn_security(conn->hcon, d->sec_level, auth_type, d->out);`,
+specifically when accessing `conn->hcon`, a null-ptr-deref error occurred.
+
+To fix this bug, check if `sk->sk_state` is BT_CLOSED before calling
+rfcomm_recv_frame in rfcomm_process_rx.

+Origin: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit?id=74ca3ef68d2f449bc848c0a814cefc487bf755fa
+Bug-Debian-Security: https://security-tracker.debian.org/tracker/CVE-2023-6270
+
+[ Upstream commit f98364e926626c678fb4b9004b75cacf92ff0662 ]
+
+This patch is against CVE-2023-6270. The description of cve is:
+
+  A flaw was found in the ATA over Ethernet (AoE) driver in the Linux
+  kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on
+  `struct net_device`, and a use-after-free can be triggered by racing
+  between the free on the struct and the access through the `skbtxq`
+  global queue. This could lead to a denial of service condition or
+  potential code execution.
+
+In aoecmd_cfg_pkts(), it always calls dev_put(ifp) when skb initial
+code is finished. But the net_device ifp will still be used in
+later tx()->dev_queue_xmit() in kthread. Which means that the
+dev_put(ifp) should NOT be called in the success path of skb
+initial code in aoecmd_cfg_pkts(). Otherwise tx() may run into
+use-after-free because the net_device is freed.
+
+This patch removed the dev_put(ifp) in the success path in
+aoecmd_cfg_pkts(), and added dev_put() after skb xmit in tx().

+Subject: efi/libstub: fix efi_random_alloc() to allocate memory at alloc_min
+ or higher address
+Origin: https://git.kernel.org/linus/3cb4a4827596abc82e55b80364f509d0fefc3051
+
+Following warning is sometimes observed while booting my servers:
+  [    3.594838] DMA: preallocated 4096 KiB GFP_KERNEL pool for atomic allocations
+  [    3.602918] swapper/0: page allocation failure: order:10, mode:0xcc1(GFP_KERNEL|GFP_DMA), nodemask=(null),cpuset=/,mems_allowed=0-1
+  ...
+  [    3.851862] DMA: preallocated 1024 KiB GFP_KERNEL|GFP_DMA pool for atomic allocation
+
+If 'nokaslr' boot option is set, the warning always happens.
+
+On x86, ZONE_DMA is small zone at the first 16MB of physical address
+space. When this problem happens, most of that space seems to be used by
+decompressed kernel. Thereby, there is not enough space at DMA_ZONE to
+meet the request of DMA pool allocation.
+
+The commit 2f77465b05b1 ("x86/efistub: Avoid placing the kernel below
+LOAD_PHYSICAL_ADDR") tried to fix this problem by introducing lower
+bound of allocation.
+
+But the fix is not complete.
+
+efi_random_alloc() allocates pages by following steps.
+1. Count total available slots ('total_slots')
+2. Select a slot ('target_slot') to allocate randomly
+3. Calculate a starting address ('target') to be included target_slot
+4. Allocate pages, which starting address is 'target'
+
+In step 1, 'alloc_min' is used to offset the starting address of memory
+chunk. But in step 3 'alloc_min' is not considered at all.  As the
+result, 'target' can be miscalculated and become lower than 'alloc_min'.
+
+When KASLR is disabled, 'target_slot' is always 0 and the problem
+happens everytime if the EFI memory map of the system meets the
+condition.
+
+Fix this problem by calculating 'target' considering 'alloc_min'.

+Subject: x86/efistub: Clear decompressor BSS in native EFI entrypoint
+Origin: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/commit?id=9274ec2003042bf0ed847cb80ffcfab543a0a33a
+
+[ Upstream commit b3810c5a2cc4a6665f7a65bed5393c75ce3f3aa2 ]
+
+The EFI stub on x86 no longer invokes the decompressor as a subsequent
+boot stage, but calls into the decompression code directly while running
+in the context of the EFI boot services.
+
+This means that when using the native EFI entrypoint (as opposed to the
+EFI handover protocol, which clears BSS explicitly), the firmware PE
+image loader is being relied upon to ensure that BSS is zeroed before
+the EFI stub is entered from the firmware.
+
+As Radek's report proves, this is a bad idea. Not all loaders do this
+correctly, which means some global variables that should be statically
+initialized to 0x0 may have junk in them.
+
+So clear BSS explicitly when entering via efi_pe_entry(). Note that
+zeroing BSS from C code is not generally safe, but in this case, the
+following assignment and dereference of a global pointer variable
+ensures that the memset() cannot be deferred or reordered.
+

+Subject: x86/efistub: Don't clear BSS twice in mixed mode
+Origin: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/commit?id=3a2a828d252f4280e15e61e0666644f1fadcf6c4
+
+[ Upstream commit df7ecce842b846a04d087ba85fdb79a90e26a1b0 ]
+
+Clearing BSS should only be done once, at the very beginning.
+efi_pe_entry() is the entrypoint from the firmware, which may not clear
+BSS and so it is done explicitly. However, efi_pe_entry() is also used
+as an entrypoint by the mixed mode startup code, in which case BSS will
+already have been cleared, and doing it again at this point will corrupt
+global variables holding the firmware's GDT/IDT and segment selectors.
+
+So make the memset() conditional on whether the EFI stub is running in
+native mode.
+
+Fixes: b3810c5a2cc4a666 ("x86/efistub: Clear decompressor BSS in native EFI entrypoint")
