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. - -Signed-off-by: Yuxuan Hu <20373622@buaa.edu.cn> -Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com> -Signed-off-by: Sasha Levin <sashal@kernel.org> ---- - net/bluetooth/rfcomm/core.c | 2 +- - 1 file changed, 1 insertion(+), 1 deletion(-) - -diff --git a/net/bluetooth/rfcomm/core.c b/net/bluetooth/rfcomm/core.c -index 8d6fce9005bd..4f54c7df3a94 100644 ---- a/net/bluetooth/rfcomm/core.c -+++ b/net/bluetooth/rfcomm/core.c -@@ -1937,7 +1937,7 @@ static struct rfcomm_session *rfcomm_process_rx(struct rfcomm_session *s) - /* Get data directly from socket receive queue without copying it. */ - while ((skb = skb_dequeue(&sk->sk_receive_queue))) { - skb_orphan(skb); -- if (!skb_linearize(skb)) { -+ if (!skb_linearize(skb) && sk->sk_state != BT_CLOSED) { - s = rfcomm_recv_frame(s, skb); - if (!s) - break; --- -2.43.0 - diff --git a/debian/patches/bugfix/all/Revert-scsi-core-Add-struct-for-args-to-execution-fu.patch b/debian/patches/bugfix/all/Revert-scsi-core-Add-struct-for-args-to-execution-fu.patch new file mode 100644 index 000000000..5e77d7985 --- /dev/null +++ b/debian/patches/bugfix/all/Revert-scsi-core-Add-struct-for-args-to-execution-fu.patch @@ -0,0 +1,198 @@ +From: Greg Kroah-Hartman <gregkh@linuxfoundation.org> +Date: Thu, 11 Apr 2024 09:26:49 +0200 +Subject: Revert "scsi: core: Add struct for args to execution functions" +Origin: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/commit?id=d1e620297a84caac1cd67615f4f4f6901527ca2b + +This reverts commit cf33e6ca12d814e1be2263cb76960d0019d7fb94 which is +commit d0949565811f0896c1c7e781ab2ad99d34273fdf upstream. + +It is known to cause problems and has asked to be dropped. + +Link: https://lore.kernel.org/r/yq1frvvpymp.fsf@ca-mkp.ca.oracle.com +Cc: Tasos Sahanidis <tasos@tasossah.com> +Cc: Ewan D.

The reported properties are either garbage or they do +not accurately reflect the characteristics of the physical storage device +attached in the case of a bridge. + +Prior to commit 1e029397d12f ("scsi: sd: Reorganize DIF/DIX code to +avoid calling revalidate twice") we would call revalidate several +times during device discovery. As a result, incorrect values would +eventually get replaced with ones accurately describing the attached +storage. When we did away with the redundant revalidate pass, several +cases were reported where devices reported nonsensical values or would +end up in write-protected state. + +An initial attempt at addressing this issue involved introducing a +delayed second revalidate invocation. However, this approach still +left some devices reporting incorrect characteristics. + +Tasos Sahanidis debugged the problem further and identified that +introducing a READ operation prior to MODE SENSE fixed the problem and that +it wasn't a timing issue. Issuing a READ appears to cause the devices to +update their state to reflect the actual properties of the storage +media. Device properties like vendor, model, and storage capacity appear to +be correctly reported from the get-go. It is unclear why these devices +defer populating the remaining characteristics. + +Match the behavior of a well known commercial operating system and +trigger a READ operation prior to querying device characteristics to +force the device to populate the mode pages. + +The additional READ is triggered by a flag set in the USB storage and +UAS drivers. We avoid issuing the READ for other transport classes +since some storage devices identify Linux through our particular +discovery command sequence. + +Link: https://lore.kernel.org/r/20240213143306.2194237-1-martin.petersen@oracle.com +Fixes: 1e029397d12f ("scsi: sd: Reorganize DIF/DIX code to avoid calling revalidate twice") +Cc: stable@vger.kernel.org +Reported-by: Tasos Sahanidis <tasos@tasossah.com> +Reviewed-by: Ewan D.
